Figure 26-73 shows all of the McSPI interface signals in master mode.
Table 26-196 describes the McSPI I/O in master mode.
Device-Level Signal Name | Module Signal Name | I/O(1) | Description |
---|---|---|---|
spim_sclk | SPICLK | O | SPIm module serial clock output |
spim_d[0] | SPIDAT[0] | O(2) | SPI Data I/O. Can be configured either as input or as output depending on MCSPI_CHxCONF[18] IS and MCSPI_CHxCONF[16] DPE0. |
spim_d[1] | SPIDAT[1] | I(2) | SPI Data I/O. Can be configured either as input or as output depending on MCSPI_CHxCONF[18] IS and MCSPI_CHxCONF[17] DPE1. |
spim_cs[i] | SPIEN[x] | O | SPIm module chip-select i output |
For the spim_sclk signals to work properly, the INPUTENABLE bit of the appropriate CTRL_CORE_PAD_x registers should be set to 0x1 because of retiming purposes.
