This section describes the MCSPI
external connections (environment).
Table 12-33 describes the MCSPI I/O signals in master mode.
Table 12-33 MCSPI I/O Signals (Master
Mode)
| Module Pin |
I/O(1) |
Description |
| SPICLK |
O |
MCSPI Serial clock output for master
mode. |
| SPIDAT[0] |
O(2) |
MCSPI Data I/O for master mode. |
| SPIDAT[1] |
I(3) |
MCSPI Data I/O for master mode. |
| SPIEN[i] |
O |
MCSPI Chip-select i output for master
mode |
(1) I = Input; O = Output
(2) Example configuration only. Can be configured either as
input or as output depending on MCSPI_CHCONF_0/1/2/3[18] IS and
MCSPI_CHCONF_0/1/2/3[16] DPE0.
(3) Example configuration only. Can be configured either as
input or as output depending on MCSPI_CHCONF_0/1/2/3[18] IS and
MCSPI_CHCONF_0/1/2/3[17] DPE1.
Table 12-34 describes the MCSPI I/O signals in slave mode.
Table 12-34 MCSPI
I/O Signals (Slave Mode)
| Module Pin |
I/O(1) |
Description |
| SPICLK |
I |
MCSPI serial clock input for slave mode. |
| SPIDAT[0] |
I(2) |
MCSPI Data I/O for slave mode. |
| SPIDAT[1] |
O(3) |
MCSPI Data I/O for slave mode. |
| SPIEN[i] |
I(4) |
MCSPI chip-select i input for slave mode. |
(1) I = Input; O = Output
(2) Example configuration only. Can be configured either as
input or as output depending on MCSPI_CHCONF_0/1/2/3[18] IS and
MCSPI_CHCONF_0/1/2/3[16] DPE0.
(3) Example configuration only. Can be configured either as
input or as output depending on MCSPI_CHCONF_0/1/2/3[18] IS and
MCSPI_CHCONF_0/1/2/3[17] DPE1.
(4) The chip-select input in slave mode can be selected
through the MCSPI_CHCONF_0/1/2/3[22-21] SPIENSLV bit field.
