Chapter 24 DG128 Port Integration Module (S12XDG128PIMV2)
24.0.5.53 Port J Reduced Drive Register (RDRJ)
Read: Anytime.
Write: Anytime.
This register configures the drive strength of each port J output pin as either full or reduced. If the port is
used as input this bit is ignored.
24.0.5.54 Port J Pull Device Enable Register (PERJ)
Read: Anytime.
Write: Anytime.
This register configures whether a pull-up or a pull-down device is activated, if the port is used as input or
as wired-OR output. This bit has no effect if the port is used as push-pull output. Out of reset a pull-up
device is enabled.
