22.4.1.8
If the pin is used as an interrupt input this register serves as a mask to the interrupt flag to enable/disable
the interrupt.
22.4.1.9
If the pin is used as an interrupt input this register holds the interrupt flag after a valid pin event.
22.4.1.10 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.
22.4.2
22.4.2.1
The BKGD pin is associated with the S12X_BDM and S12X_EBI modules. During reset, the BKGD pin
is used as MODC input.
22.4.2.2
Port A pins PA[7:0] and Port B pins PB[7:0] can be used for either general-purpose I/O, or, in 144-pin
packages, also with the external bus interface. In this case port A and port B are associated with the
external address bus outputs ADDR15–ADDR8 and ADDR7–ADDR0, respectively. PB0 is the ADDR0
or UDS output.

The purpose of the module routing register is to provide maximum
flexibility for derivatives with a lower number of MSCAN and SPI modules.
