Chapter 23 DQ256 Port Integration Module (S12XDQ256PIMV2)
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.
23.0.5.27 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.
23.0.5.28 Port S Polarity Select Register (PPSS)
Read: Anytime.
Write: Anytime.
This register selects whether a pull-down or a pull-up device is connected to the pin.
