Chapter 2 Port Integration Module (S12XEPIMV1)
2.4.2.4
If the pin is used as an output this register allows the configuration of the drive strength.
2.4.2.5
This register turns on a pull-up or pull-down device.
It becomes active only if the pin is used as an input or as a wired-or output.
2.4.2.6
This register selects either a pull-up or pull-down device if enabled.
It becomes only active if the pin is used as an input. A pull-up device can be activated if the pin is used as
a wired-or output.
2.4.2.7
If the pin is used as an output this register turns off the active high drive. This allows wired-or type
connections of outputs.
2.4.2.8
If the pin is used as an interrupt input this register serves as a mask to the interrupt flag to enable/disable
the interrupt.
