Chapter 22 DP512 Port Integration Module (S12XDP512PIMV2)
22.3.2.41 Port P Reduced Drive Register (RDRP)
Read: Anytime.
Write: Anytime.
This register configures the drive strength of each port P output pin as either full or reduced. If the port is
used as input this bit is ignored.
22.3.2.42 Port P Pull Device Enable Register (PERP)
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.
This bit has no effect if the port is used as output. Out of reset no pull device is enabled.
