Chapter 1 Device Overview MC9S12XE-Family

1.2.3.52 PM7 / TXCAN3 / TXCAN4 / TXD3 â Port M I/O Pin 7

PM7 is a general-purpose input or output pin. It can be conï¬gured as the transmit pin TXCAN of the

scalable controller area network controller 3 or 4 (CAN3 or CAN4). PM7 can be conï¬gured as the transmit

pin TXD3 of the serial communication interface 3 (SCI3).

1.2.3.53 PM6 / RXCAN3 / RXCAN4 / RXD3 â Port M I/O Pin 6

PM6 is a general-purpose input or output pin. It can be conï¬gured as the receive pin RXCAN of the

scalable controller area network controller 3 or 4 (CAN3 or CAN4). PM6 can be conï¬gured as the receive

pin RXD3 of the serial communication interface 3 (SCI3).

1.2.3.54 PM5 / TXCAN0 / TXCAN2 / TXCAN4 / SCK0 â Port M I/O Pin 5

PM5 is a general-purpose input or output pin. It can be conï¬gured as the transmit pin TXCAN of the

scalable controller area network controllers 0, 2 or 4 (CAN0, CAN2, or CAN4). It can be conï¬gured as

the serial clock pin SCK of the serial peripheral interface 0 (SPI0).

1.2.3.55 PM4 / RXCAN0 / RXCAN2 / RXCAN4 / MOSI0 â Port M I/O Pin 4

PM4 is a general-purpose input or output pin. It can be conï¬gured as the receive pin RXCAN of the

scalable controller area network controllers 0, 2, or 4 (CAN0, CAN2, or CAN4). It can be conï¬gured as

the master output (during master mode) or slave input pin (during slave mode) MOSI for the serial

peripheral interface 0 (SPI0).

1.2.3.56 PM3 / TXCAN1 / TXCAN0 / SS0 â Port M I/O Pin 3

PM3 is a general-purpose input or output pin. It can be conï¬gured as the transmit pin TXCAN of the

scalable controller area network controllers 1 or 0 (CAN1 or CAN0). It can be conï¬gured as the slave

select pin SS of the serial peripheral interface 0 (SPI0).

1.2.3.57 PM2 / RXCAN1 / RXCAN0 / MISO0 â Port M I/O Pin 2

PM2 is a general-purpose input or output pin. It can be conï¬gured as the receive pin RXCAN of the

scalable controller area network controllers 1 or 0 (CAN1 or CAN0). It can be conï¬gured as the master

input (during master mode) or slave output pin (during slave mode) MISO for the serial peripheral

interface 0 (SPI0).

1.2.3.58 PM1 / TXCAN0 â Port M I/O Pin 1

PM1 is a general-purpose input or output pin. It can be conï¬gured as the transmit pin TXCAN of the

scalable controller area network controller 0 (CAN0).

1.2.3.59 PM0 / RXCAN0 â Port M I/O Pin 0

PM0 is a general-purpose input or output pin. It can be conï¬gured as the receive pin RXCAN of the

scalable controller area network controller 0 (CAN0).
