Pins and Connections
2.2.1
SCI1 and SCI2 are designed with twice the normal I/O drive capability on the TX pins. The RX pins can
either be fed directly from the digital I/O buffer, or those signals can be pre-conditioned using comparators
1 and 2 as shown in
timers before being passed off chip.

This is the default SCI Rx digital input.
The TPM channels have to be configured to Toggle on output compare. The TPM channel pins can be used
as regular GPIOs. Please see configurations in
SCI1/2
(SIMIPS2).”
