2.3.8.3 DSPI A Data Output / DSPI C Chip Select / GPIO
SOUTA_PCSC[5]_GPIO[95]
SOUTA_PCSC[5]_GPIO[95] has a primary signal function of source data output SOUTA 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 SOUTA is not available on the MPC5553. The peripheral chip select output
for the DSPI C module PCSC[5] is the alternate signal function. This pin can also be used as a GPIO signal.
2.3.8.4 DSPI A Chip Select / DSPI D Chip Select / GPIO
PCSA[0]_PCSD[2]_GPIO[96]
PCSA[0]_PCSD[2]_GPIO[96] has a primary signal function of peripheral chip select output for the DSPI
A module for the MPC5554, PCSA[0] also serves as the slave select input (SS) of the DSPI A module.
Because the MPC5553 does not have a DSPI A module, the primary signal function PCSA[0] is not
available on the MPC5553. The peripheral chip select output for the DSPI D module PCSD[2] is the
alternate signal function. This pin can also be used as a GPIO signal.
2.3.8.5 DSPI A Chip Select / DSPI B Chip Select / GPIO
PCSA[1]_PCSB[2]_GPIO[97]
PCSA[1]_PCSB[2]_GPIO[97] has a primary signal function of PCSA[1] that is a peripheral select output
for the DSPI A module for the MPC5554. Because the MPC5553 does not have a DSPI A module, the
primary signal function PCSA[1] is not available on the MPC5553. The peripheral chip select output for
the DSPI B module PCSB[2] is the alternate signal function. This pin can also be used as a GPIO signal.
2.3.8.6 DSPI A Chip Select / DSPI D Clock / GPIO
PCSA[2]_SCKD_GPIO[98]
PCSA[2]_SCKD_GPIO[98] has a primary signal function of PCSA[2] that is a peripheral select output for
the DSPI A module for the MPC5554. Because the MPC5553 does not have a DSPI A module, the primary
signal function PCSA[2] is not available on the MPC5553. SCKD is the alternate signal function and is
the SPI clock for the DSPI D module. This pin can also be used as a GPIO signal.
2.3.8.7 DSPI A Chip Select / DSPI D Data Input / GPIO
PCSA[3]_SIND_GPIO[99]
PCSA[3]_SIND_GPIO[99] has a primary function of PCSA[3] that is a peripheral select output pin for the
DSPI A module for the MPC5554. Because the MPC5553 does not have a DSPI A module, the primary
signal function PCSA[3] is not available on the MPC5553. The SPI input for the DSPI D module SIND is
the alternate function and is the SPI input. This pin can also be used as a GPIO signal.
2.3.8.8 DSPI A Chip Select / DSPI D Data Output / GPIO
PCSA[4]_SOUTD_GPIO[100]
PCSA[4]_SOUTD_GPIO[100] has a primary function of 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[4] is not available on the MPC5553. The SPI output for the DSPI D
module is the alternate function.
