2.3.33 PK[5:0] / XADDR[19:14] — Port K I/O Pins [5:0]
PK5-PK0 are general purpose input or output pins. In MCU expanded modes of operation, these pins
provide the expanded address XADDR[19:14] for the external bus.
2.3.34 PM7 / TXCAN4 — Port M I/O Pin 7
PM7 is a general purpose input or output pin. It can be configured as the transmit pin TXCAN of the
Motorola Scalable Controller Area Network controller 4 (CAN4 ).
2.3.35 PM6 / RXCAN4 — Port M I/O Pin 6
PM6 is a general purpose input or output pin. It can be configured as the receive pin RXCAN of the
Motorola Scalable Controller Area Network controller 4 (CAN4).
2.3.36 PM5 / TXCAN0 / TXCAN4 / SCK0 — Port M I/O Pin 5
PM5 is a general purpose input or output pin. It can be configured as the transmit pin TXCAN of the
Motorola Scalable Controller Area Network controllers 0 or 4 (CAN0 or CAN4). It can be configured as
the serial clock pin SCK of the Serial Peripheral Interface 0 (SPI0).
2.3.37 PM4 / RXCAN0 / RXCAN4/ MOSI0 — Port M I/O Pin 4
PM4 is a general purpose input or output pin. It can be configured as the receive pin RXCAN of the
Motorola Scalable Controller Area Network controllers 0 or 4 ( CAN0 or CAN4). It can be configured as
the master output (during master mode) or slave input pin (during slave mode) MOSI for the Serial
Peripheral Interface 0 (SPI0).
2.3.38 PM3 / TXCAN1 / TXCAN0 / SS0 — Port M I/O Pin 3
PM3 is a general purpose input or output pin. It can be configured as the transmit pin TXCAN of the
Motorola Scalable Controller Area Network controllers 1 or 0 (CAN1 or CAN0). It can be configured as
the slave select pin SS of the Serial Peripheral Interface 0 (SPI0).
2.3.39 PM2 / RXCAN1 / RXCAN0 / MISO0 — Port M I/O Pin 2
PM2 is a general purpose input or output pin. It can be configured as the receive pin RXCAN of the
Motorola Scalable Controller Area Network controllers 1 or 0 (CAN1 or CAN0). It can be configured as
the master input (during master mode) or slave output pin (during slave mode) MISO for the Serial
Peripheral Interface 0 (SPI0).
