Freescale Semiconductor 2-27
2.3.5.6 FlexCAN A Receive / DSPI D / GPIO
CNRXC_PCSD[4]_GPIO[88]
CNRXC_PCSD[4]_GPIO[88] is the receive pin for the FlexCAN C module. The alternate function is
PCSD[4], a peripheral chip select for the DSPI D module.
2.3.6 Enhanced Serial Communications Interface (eSCI) Signals
2.3.6.1 eSCI A Transmit / GPIO
TXDA_GPIO[89]
TXDA_GPIO[89] is the transmit data pin for the eSCI A module.
2.3.6.2 eSCI A Receive / GPIO
RXDA_GPIO[90]
RXDA_GPIO[90] is the receive pin for the eSCI A module. The pin is an input only for the receive data
function, but as GPIO the pin is input or output based on the SIU PCR configuration.
2.3.6.3 eSCI B Transmit / DSPI D / GPIO
TXDB_PCSD[1]_GPIO[91]
TXDB_PCSD[1]_GPIO[91] is the transmit pin for the eSCI B module. The alternate function is a
peripheral chip select output for the DSPI D module.
2.3.6.4 eSCI B Receive / DSPI D / GPIO
RXDB_PCSD[5]_GPIO[92]
RXDB_PCSD[5]_GPIO[92] is the transmit pin for the eSCI B module. The secondary function is a
peripheral chip select for the DSPI D module.
2.3.7 Deserial/Serial Peripheral Interface (DSPI) Signals
2.3.7.1 DSPI A Clock / DSPI C / GPIO
SCKA_PCSC[1]_GPIO[93]
SCKA_PCSC[1]_GPIO[93] — SCKA is the primary function and is the SPI clock pin for the DSPI A
module. The alternate signal function is the PCSC[1], a peripheral chip select for the DSPI C module.
2.3.7.2 DSPI A Data Input / DSPI C / GPIO
SINA_PCSC[2]_GPIO[94]
SINA_PCSC[2]_GPIO[94] — SINA is the primary function and is the data input pin for the DSPI A
module. The alternate signal function is PCSC[2], a peripheral chip select for the DSPI C module.
