PM4 / RXCAN0 / RXCAN2 / 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
scalable controller area network controllers 0, 2, or 4 (CAN0, CAN2, 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).
1.2.3.48
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
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).
1.2.3.49
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
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).
1.2.3.50
PM1 / TXCAN0 — 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
scalable controller area network controller 0 (CAN0).
1.2.3.51
PM0 / RXCAN0 — 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
scalable controller area network controller 0 (CAN0).
