2.3.30 PJ6 / KWJ6 / RXCAN4 / SDA — PORT J I/O Pin 6
PJ6 is a general purpose input or output pin. It can be configured to generate an interrupt causing the MCU
to exit STOP or WAIT mode. It can be configured as the receive pin RXCAN for the Motorola Scalable
Controller Area Network controller 4 (CAN4) or the serial data pin SDA of the IIC module.
2.3.31 PJ[1:0] / KWJ[1:0] — Port J I/O Pins [1:0]
PJ1 and PJ0 are general purpose input or output pins. They can be configured to generate an interrupt
causing the MCU to exit STOP or WAIT mode .
2.3.32 PK7 / ECS / ROMONE — Port K I/O Pin 7
PK7 is a general purpose input or output pin. During MCU expanded modes of operation, this pin is used
as the emulation chip select output (ECS). During MCU normal expanded wide and narrow modes of
operation, this pin is used to enable the Flash EEPROM memory in the memory map (ROMONE). 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
Motorola 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
Motorola 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
Motorola 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
Motorola 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).
