2.3.8.9 DSPI A Chip Select / DSPI B Chip Select / GPIO
PCSA[5]_PCSB[3]_GPIO[101]
PCSA[5]_PCSB[3]_GPIO[101] is a peripheral chip select output pin for the DSPI A module and is only
available on the MPC5554. Because the MPC5553 does not have a DSPI A module, the primary signal
function PCSA[5] is not available on the MPC5553. The SPI output for the DSPI B module is the alternate
function. This pin can also be used as a GPIO signal.
2.3.8.10 DSPI B Clock / DSPI C Chip Select / GPIO
SCKB_PCSC[1]_GPIO[102]
SCKB_PCSC[1]_GPIO[102] is the SPI clock pin for the DSPI B module. The alternate function is a chip
select output for the DSPI C module. This pin can also be used as a GPIO signal.
2.3.8.11 DSPI B Data Input / DSPI C Chip Select / GPIO
SINB_PCSC[2]_GPIO[103]
SINB_PCSC[2]_GPIO[103] is the data input pin for the DSPI B module. The alternate function is a chip
select output for the DSPI C module. This pin can also be used as a GPIO signal.
2.3.8.12 DSPI B Data Output / DSPI C Chip Select / GPIO
SOUTB_PCSC[5]_GPIO[104]
SOUTB_PCSC[5]_GPIO[104] is the data output pin for the DSPI B module. The alternate function is a
chip select output for the DSPI C module. This pin can also be used as a GPIO signal.
2.3.8.13 DSPI B Chip Select / DSPI D Chip Select / GPIO
PCSB[0]_PCSD[2]_GPIO[105]
PCSB[0]_PCSD[2]_GPIO[105] is a peripheral chip select output pin (slave select input pin for slave
operation) for the DSPI B module. The alternate function is a chip select output for the DSPI D module.
This pin can also be used as a GPIO signal.
2.3.8.14 DSPI B Chip Select / DSPI D Chip Select / GPIO
PCSB[1]_PCSD[0]_GPIO[106]
PCSB[1]_PCSD[0]_GPIO[106] is a peripheral chip select output pin for the DSPI B module. The alternate
function is a chip select output (slave select input pin for slave operation) for the DSPI D module. This pin
can also be used as a GPIO signal.
2.3.8.15 DSPI B Chip Select / DSPI C Data Output / GPIO
PCSB[2]_SOUTC_GPIO[107]
PCSB[2]_SOUTC_GPIO[107] is a peripheral chip select output pin for the DSPI B module. The alternate
function is the data output for the DSPI C module. This pin can also be used as a GPIO signal.
