Signal Name
Description
TXDC_ETRIG0_GPIO244
Transmit data pin for the eSCI C module. The alternate function is external trigger signal
to trigger a software or hardware event. The eQADC can detect rising edge, falling edge,
high level, and low level on each of the external trigger signals. The eQADC also supports
configurable digital filters for these external trigger signals. The eQADC external trigger
input pins can be connected to the eTPU, the eMIOS, or an external signal. The source is
selected by configuring the eQADC trigger source in the SIU_ISEL4-7 registers.
ETRIG[0] is the external trigger for CFIFO0, CFIFO2, and CFIFO4

Receive pin for the eSCI C module.
This pin does not have a primary function assigned to it. The alternate function is the
transmit pin for the eSCI A module
This pin does not have a primary function assigned to it. The alternate function is the
receive pin for the eSCI A module
This pin does not have a primary function assigned to it. The alternate function is the
transmit pin for the eSCI B module
This pin does not have a primary function assigned to it. The alternate function is the
receive pin for the eSCI B module

select for the DSPI C module
Data output pin for the DSPI A module. The alternate signal function is a peripheral chip
select for the DSPI C module
Peripheral chip select for the DSPI A module. The alternate signal function is a peripheral
chip select for the DSPI D module
Peripheral chip selects for the DSPI A module.
Peripheral chip select for the DSPI A module. Alternate function is external trigger signal
to trigger a software or hardware event. The eQADC can detect rising edge, falling edge,
high level, and low level on each of the external trigger signals. The eQADC also supports
configurable digital filters for these external trigger signals.
The eQADC external trigger input pins can be connected to the eTPU, the eMIOS, or an
external signal. The source is selected by configuring the eQADC trigger source in the
SIU_ISEL4-7 registers.
ETRIG[1] serves as the external trigger for CFIFO1, CFIFO3, and CFIFO5.
