Chapter 24 DG128 Port Integration Module (S12XDG128PIMV2)
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.
24.0.5.31 Port M Polarity Select Register (PPSM)
Read: Anytime.
Write: Anytime.
This register selects whether a pull-down or a pull-up device is connected to the pin. If CAN is active, a
pull-up device can be activated on the related RXCAN inputs, but not a pull-down.
24.0.5.32 Port M Wired-OR Mode Register (WOMM)
Read: Anytime.
Write: Anytime.
