PM7 / TXCAN3 / TXCAN4 / TXD3 — Port M I/O Pin 7

Because of an order from the United States International Trade Commission, BGA-packaged product lines and part numbers indicated here currently are not

available from Freescale for import or sale in the United States prior to September 2010: S12XE products in 208 MAPBGA packages

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

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

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

1.2.3.53

PM6 / RXCAN3 / RXCAN4 / RXD3 — Port M I/O Pin 6

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

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

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

1.2.3.54

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

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

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

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

1.2.3.55

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).

1.2.3.56

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).

1.2.3.57

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).

1.2.3.58

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).

1.2.3.59

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).
