2.3.29 PJ6 / KWJ6 / RXCAN4 / SDA / RXCAN0 — 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 0 or 4 (CAN0, CAN4) or the serial data pin SDA of the IIC module.

2.3.30 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.

2.3.31 PK7 / ECS / ROMCTL — 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). While configurating MCU expanded modes, this pin is 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. For a complete list of modes refer to 4.2 Chip Configuration

Summary.

2.3.32 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.

2.3.33 PM7 / BF_PSLM / TXCAN4 — Port M I/O Pin 7

PM7 is a general purpose input or output pin. It can be configured as the slot mismatch output pulse pin

of Byteflight. It can be configured as the transmit pin TXCAN of the Motorola Scalable Controller Area

Network controllers 4 (CAN4).

2.3.34 PM6 / BF_PERR / RXCAN4 — Port M I/O Pin 6

PM6 is a general purpose input or output pin. It can be configured as the illegal pulse or message format

error output pulse pin of Byteflight. It can be configured as the receive pin RXCAN of the Motorola

Scalable Controller Area Network controllers 4 (CAN4).

2.3.35 PM5 / BF_PROK / TXCAN0 / TXCAN4 / SCK0 — Port M I/O Pin 5

PM5 is a general purpose input or output pin. It can be configured as the reception OK output pulse pin of

Byteflight. 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).
