Chapter 24 DG128 Port Integration Module (S12XDG128PIMV2)
24.0.6.4
If the pin is used as an output this register allows the configuration of the drive strength.
24.0.6.5
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.
24.0.6.6
This register selects either a pull-up or pull-down device if enabled. It becomes active only 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 interrupt input this register selects the active interrupt edge.
24.0.6.7
If the pin is used as an output this register turns off the active high drive. This allows wired-OR type
connections of outputs.
24.0.6.8
If the pin is used as an interrupt input this register serves as a mask to the interrupt flag to enable/disable
the interrupt.
24.0.6.9
If the pin is used as an interrupt input this register holds the interrupt flag after a valid pin event.
24.0.6.10 Module Routing Register
This register supports the re-routing of the CAN0, CAN4, SPI0, SPI1, and SPI2 pins to alternative ports.
This allows a software re-configuration of the pinouts of the different package options with respect to
above peripherals.

Reduced Drive Register
Pull Device Enable Register
Polarity Select Register
Wired-OR Mode Register
Interrupt Enable Register
Interrupt Flag Register
The purpose of the module routing register is to provide maximum
flexibility for derivatives with a lower number of MSCAN and SPI modules.
