Chapter 24 DG128 Port Integration Module (S12XDG128PIMV2)
The DDRT bits revert to controlling the I/O direction of a pin when the associated timer output compare
is disabled.
The timer input capture always monitors the state of the pin.
24.0.5.16 Port T Reduced Drive Register (RDRT)
Read: Anytime.
Write: Anytime.
This register configures the drive strength of each port T output pin as either full or reduced. If the port is
used as input this bit is ignored.
24.0.5.17 Port T Pull Device Enable Register (PERT)
Read: Anytime.
Write: Anytime.
