2.3.36 PM4 / BF_PSYN / RXCAN0 / RXCAN4/ MOSI0 — Port M I/O Pin 4

PM4 is a general purpose input or output pin. It can be configured as the correct synchronisation pulse

reception/transmission output pulse pin of Byteflight. 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).

2.3.37 PM3 / TX_BF / 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 pinTX_BF of Byteflight.

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).

2.3.38 PM2 / RX_BF / 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 RX_BF of Byteflight.

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).

2.3.39 PM1 / TXCAN0 / TXB — Port M I/O Pin 1

PM1 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 0 (CAN0). It can be configured as the transmit pin

TXB of the BDLC.

2.3.40 PM0 / RXCAN0 / RXB — Port M I/O Pin 0

PM0 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 0 (CAN0). It can be configured as the receive pin

RXB of the BDLC.

2.3.41 PP7 / KWP7 / PWM7 — Port P I/O Pin 7

PP7 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 Pulse Width Modulator (PWM) channel 7 output.

2.3.42 PP6 / KWP6 / PWM6 — Port P I/O Pin 6

PP6 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 Pulse Width Modulator (PWM) channel 6 output.
