Chapter 22 DP512 Port Integration Module (S12XDP512PIMV2)
22.3.2.26 Port S Reduced Drive Register (RDRS)
Read: Anytime.
Write: Anytime.
This register configures the drive strength of each port S output pin as either full or reduced. If the port is
used as input this bit is ignored.
22.3.2.27 Port S Pull Device Enable Register (PERS)
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 output in wired-OR (open drain) mode. This bit has no effect if the port is used as push-pull output. Out
of reset a pull-up device is enabled.
