The Port Integration Module establishes the interface between the
peripheral modules and the I/O pins for all ports except A, B, E and K.
Ports A, B, E and K are handled by the HC12 multiplexed bus interface
and described in Multiplexed External Bus Interface (MEBI) section on
page 141, due to their tight link with the external bus interface and
special modes.
The 8-bit port associated with the ATD is included in the ATD module
due to their sensitivity to electrical noise, requiring special care on
routing and design.
This section covers port T connected to the timer module, the serial
port S associated with 2 SCI and 1 SPI module and port P connected to
the PWM.
Each I/O pin is associated with a set of registers which configure items
like input/output selection, drive strength reduction, and pull resistors
enable and selection.
