Chapter 22 DP512 Port Integration Module (S12XDP512PIMV2)
22.3.2.33 Port M Reduced Drive Register (RDRM)
Read: Anytime.
Write: Anytime.
This register configures the drive strength of each Port M output pin as either full or reduced. If the port
is used as input this bit is ignored.
22.3.2.34 Port M Pull Device Enable Register (PERM)
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
wired-OR output. This bit has no effect if the port is used as push-pull output. Out of reset no pull device
is enabled.
