9.5.7 Modem Control Register (MCR)

The MCR controls the interface with the modem, data set, or peripheral device that is emulating the modem. Table 17 shows modem control register bit settings.

Table 17. MCR Bit Settings(1)

BIT BIT SETTINGS
0 0 = Force DTR output to inactive (high)
1 = Force DTR output to active (low). In loopback controls MSR[5]
1 0 = Force RTS output to inactive (high)
1 = Force RTS output to active (low)
In loopback controls MSR[4]
If Auto-RTS is enabled the RTS output is controlled by hardware flow control
2 0 Disables the FIFORdy register
1 Enable the FIFORdy register
In loopback controls MSR[6]
3 0 = Forces the INT output to high-impedance state
1 = Forces the INT output to the active state
In loopback controls MSR[7]
4 0 = Normal operating mode
1 = Enable local loopback mode (internal)
In this mode, the MCR[3:0] signals are looped back into MSR[3:0] and the TX output is looped back to the RX input internally
5 0 = Disable Xon Any function
1 = Enable Xon Any function
6 0 = No action
1 = Enable access to the TCR and TLR registers
7 0 = Divide by one clock input
1 = Divide by four clock input
(1) MCR[7:5] can be modified only when EFR[4] is set, that is, EFR[4] is a write enable.
