2.3.29 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.
2.3.30 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). During MCU expanded modes of operation, 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).
