used to enable the Flash EEPROM memory in the memory map (ROMCTL). At the rising edge of RESET,
the state of this pin is latched to the ROMON bit.
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 / TXCAN3 / 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
Freescale Scalable Controller Area Network controllers 3 or 4 (CAN3 or CAN4).
2.3.35 PM6 / RXCAN3 / 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
Freescale Scalable Controller Area Network controllers 3 or 4 (CAN3 or CAN4).
2.3.36 PM5 / TXCAN2 / 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
Freescale Scalable Controller Area Network controllers 2, 0 or 4 (CAN2, CAN0 or CAN4). It can be
configured as the serial clock pin SCK of the Serial Peripheral Interface 0 (SPI0).
2.3.37 PM4 / RXCAN2 / 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
Freescale Scalable Controller Area Network controllers 2, 0 or 4 (CAN2, 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
Freescale 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
Freescale 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).
