EST Fill Enable.
Enable EST fill mode.

7-5EST_TS_PRIR/W0h

EST Timestamp Express Priority.
Selects the express priority that timestamp(s) will be generated on when CPSW_PN_EST_CONTROL_REG[4] EST_TS_ONEPRI bit is set.

4EST_TS_ONEPRIR/W0h

EST Timestamp One Express Priority.
When set, timestamp only enabled packets on the express priority selected by CPSW_PN_EST_CONTROL_REG[7-5] ST_TS_PRI bit field.
When cleared to zero, express packet selection for timestamp is independent of priority.

3EST_TS_FIRSTR/W0h

EST Timestamp First Express Packet only.
Generate a timestamp only on the first selected express packet in each EST time interval when express timestamps are enabled.
(If CPSW_PN_EST_CONTROL_REG[4] EST_TS_ONEPRI is also set then the timestamp is generated only on the first packet on CPSW_PN_EST_CONTROL_REG[7-5] ST_TS_PRI).

2EST_TS_ENR/W0h

EST Timestamp Enable.
Enable express timestamps (when CPSW_CONTROL_REG[18] EST_ENABLE and CPSW_PN_CONTROL_REG[17] EST_PORT_EN bits are set).

1EST_BUFSELR/W0h

EST Buffer Select.
If CPSW_PN_EST_CONTROL_REG[0] EST_ONEBUF is cleared, this bit selects the upper (when set) or the lower (when cleared) 64-word fetch buffer.
The actual fetch buffer used changes only at the start of the EST time interval and can be read in the CPSW_PN_FIFO_STATUS_REG register, bit [18] EST_BUFACT.

0EST_ONEBUFR/W0h

EST One Fetch Buffer.
When set indicates that all 128 fetch words are used in one buffer.
When cleared, indicates that the 128 fetch words are split into two 64-word fetch buffers. The CPSW_PN_EST_CONTROL_REG[1] EST_BUFSEL bit selects the buffer to be used when bit [0] EST_ONEBUF is cleared to zero.

24RX_CMF_ENR/W0h

RX Copy MAC Control Frames Enable.
Enables MAC control frames to be transferred to memory.
MAC control frames are normally acted upon (if enabled), but not copied to memory. MAC control frames that are pause frames will be acted upon if enabled in the CPSW_PN_MAC_CONTROL_REG register, regardless of the value of [24] RX_CMF_EN bit. Frames transferred to memory due to [24] RX_CMF_EN will have the control bit set in their EOP buffer descriptor.
0h = MAC control frames are filtered (but acted upon if enabled).
1h = MAC control frames are transferred to memory.

23RX_CSF_ENR/W0h

RX Copy Short Frames Enable.
Enables frames or fragments shorter than 64 bytes to be copied to memory.
Frames transferred to memory due to CPSW_PN_MAC_CONTROL_REG[23] RX_CSF_EN will have the fragment or undersized bit set in their receive footer. Fragments are short frames that contain CRC/align/code errors and undersized are short frames without errors.
0h = Short frames are filtered.
1h = Short frames are transferred to memory.

22RX_CEF_ENR/W0h

RX Copy Error Frames Enable.
Enables frames containing errors to be transferred to memory.
The appropriate error bit will be set in the frame receive footer. Frames containing errors will be filtered when CPSW_PN_MAC_CONTROL_REG[22] RX_CEF_EN is not set.
0h = Frames containing errors are filtered.
1h = Frames containing errors are transferred to memory.

21TX_SHORT_GAP_LIM_ENR/W0h

Transmit Short Gap Limit Enable
When set this bit limits the number of short gap packets transmitted to 100ppm. Each time a short gap packet is sent, a counter is loaded with 10,000 and decremented on each wireside clock. Another short gap packet will not be sent out until the counter decrements to zero. This mode is included to preclude the host from filling up the FIFO and sending every packet out with short gap which would violate the maximum number of packets per second allowed. This bit is used only with GMII (not XGMII).

20EXT_TX_FLOW_ENR/W0h

External Transmit Flow Control Enable.
Enables the TX_FLOW_EN to be selected from the EXT_TX_FLOW_EN input signal and not from the [4] TX_FLOW_EN bit in CPSW_PN_MAC_CONTROL_REG register.

19EXT_RX_FLOW_ENR/W0h

External Receive Flow Control Enable.
Enables the RX_FLOW_EN to be selected from the EXT_RX_FLOW_EN input signal and not from the CPSW_PN_MAC_CONTROL_REG[3] RX_FLOW_EN bit in this register.

18CTL_ENR/W0h

External Control Enable.
Enables the fullduplex and gigabit mode to be selected from the FULLDUPLEX_IN and GIG_IN input signals and not from the [0] FULLDUPLEX and [7] GIG bits in the CPSW_PN_MAC_CONTROL_REG register.
The [0] FULLDUPLEX bit reflects the actual fullduplex mode selected.

17GIG_FORCER/W0h

4TX_FLOW_ENR/W0h

Transmit Flow Control Enable.
Determines if incoming pause frames are acted upon in full-duplex mode.
Incoming pause frames are not acted upon in half-duplex mode regardless of this bit setting. The RX_MBP_ENABLE bits determine whether or not received pause frames are transferred to memory.
0h = Transmit Flow Control Disabled.
Full-duplex mode – Incoming pause frames are not acted upon.
1h = Transmit Flow Control Enabled.
Full-duplex mode – Incoming pause frames are acted upon.

3RX_FLOW_ENR/W0h

Receive Flow Control Enable.
0h = Receive Flow Control Disabled
Half-duplex mode – No flow control generated collisions are sent.
Full-duplex mode – No outgoing pause frames are sent.
1h = Receive Flow Control Enabled
Half-duplex mode – Collisions are initiated when receive flow control is triggered.
Full-duplex mode – Outgoing pause frames are sent when receive flow control is triggered.

2MTESTR/W0h

Manufacturing Test mode.
This bit must be set to allow writes to the CPSW_PN_MAC_BOFFTEST_REG and CPSW_PN_MAC_RX_PAUSETIMER_REG registers.

1LOOPBACKR/W0h

Loop Back Mode.
Loopback mode forces internal fullduplex mode regardless of whether the CPSW_PN_MAC_CONTROL_REG[0] FULLDUPLEX bit is set or not.
The [1] LOOPBACK bit should be changed only when [5] GMII_EN is de-asserted. Loopback is used only with GMII (not XGMII). Loopback is not compatible with timestamp operations (CPTS).
0h = Not looped back mode

Pacing Current Value.
A non-zero value in this field indicates that transmit pacing is active. A transmit frame collision or deferral causes paceval to loaded with decimal 31, good frame transmissions (with no collisions or deferrals) cause paceval to be decremented down to zero.
When paceval is nonzero, the transmitter delays 4 IPGs between new frame transmissions after each successfully transmitted frame that had no deferrals or collisions. Transmit pacing helps reduce “capture” effects improving overall network bandwidth.

This field allows the contents of the receive pause timer to be observed (and written in test mode).
The receive pause timer is loaded with FF00h when the Ethernet port sends an outgoing pause frame (with pause time of FFFFh). The receive pause timer is decremented at slot time intervals. If the receive pause timer decrements to zero, then another outgoing pause frame will be sent and the load/decrement process will be repeated. This register is for 802.3 Based flow control and is not used for 802.1qbb Priority Based Flow Control (PFC).

Transmit Inter-Packet Gap
GMII modes – This is the default gap value and only bits [8-0] are used. This can be increased from 12 to increase the gap between packets.
XGMII mode – In 10 Gigabit mode this is the short gap rate and should be changed to 5000 (1388h) to get approximately 200ppm faster when short gap is triggered and enabled.
