Chapter 2 Port Integration Module (S12XEPIMV1)

If the pin is used as an output this register allows the conﬁguration of the drive strength.

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.

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.

If the pin is used as an output this register turns off the active high drive. This allows wired-or type

connections of outputs.

If the pin is used as an interrupt input this register serves as a mask to the interrupt ﬂag to enable/disable

the interrupt.
