The MCU_PORT1 provides access to the peripheral
features and I/O lines of the HC12.  Note:

1) Not all I/O Ports are provided by all HC12 MCUs.

2) The PX0 - PX7 port is the CAN channel port and

additional I/O provided by the HC12 devices
associated with that port.  Some devices designate
this port as PCAN, PIB, ect.

3) The PG/PJx  ports provide either the HC12 port G

or HC12 port J depending on device installed.
