The MCU_PORT provides access to the peripheral features and I/O lines of the HCS12.
**Note signals with alternate connections on the development board:
PB0 - 7 [D0 - 7] provide address / data on the expanded HCS12.
PK0 - 5 [XA14 - XA19] provide high order paged address lines on the expanded HCS12.
PM0 - 1 [CAN RXD0, TXD0] CAN channel 0 to CAN Port transceiver.
PS0 - 1 [COM Port RXD0, TXD0]
PS2 - 3 [JP3 Port RXD1, TXD2]
PS4 - 7 [SPI Port] provides LCD_PORT serial interface.
