Chapter 23 DQ256 Port Integration Module (S12XDQ256PIMV2)
23.0.5.30 Port M Data Register (PTM)
Read: Anytime.
Write: Anytime.
Port M pins 7–0 are associated with the CAN0, CAN1, CAN2, as well as the routed CAN0, CAN4, and
SPI0 modules. When not used with any of the peripherals, these pins can be used as general purpose I/O.
If the data direction bits of the associated I/O pins are set to logic level “1”, a read returns the value of the
port register, otherwise the buffered pin input state is read.

The CAN4 function (TXCAN4 and RXCAN4) takes precedence over the general purpose I/O function if the CAN4
module is enabled. Refer to MSCAN section for details.
The CAN2 function (TXCAN2 and RXCAN2) takes precedence over the routed CAN0, routed CAN4, the routed
SPI0 and the general purpose I/O function if the CAN2 module is enabled.
The routed CAN0 function (TXCAN0 and RXCAN0) takes precedence over the routed CAN4, the routed SPI0
and the general purpose I/O function if the routed CAN0 module is enabled.
The routed CAN4 function (TXCAN4 and RXCAN4) takes precedence over the routed SPI0 and general purpose
I/O function if the routed CAN4 module is enabled. Refer to MSCAN section for details.
The routed SPI0 function (SCK0 and MOSI0) takes precedence of the general purpose I/O function if the routed
SPI0 is enabled. Refer to SPI section for details.
The CAN1 function (TXCAN1 and RXCAN1) takes precedence over the routed CAN0, the routed SPI0 and the
general purpose I/O function if the CAN1 module is enabled.The routed CAN0 function (TXCAN0 and RXCAN0)
takes precedence over the routed SPI0 and the general purpose I/O function if the routed CAN0 module is
enabled. Refer to MSCAN section for details.
The routed SPI0 function (SS0 and MISO0) takes precedence of the general purpose I/O function if the routed
SPI0 is enabled and not in bidirectional mode. Refer to SPI section for details.
The CAN0 function (TXCAN0 and RXCAN0) takes precedence over the general purpose I/O function if the CAN0
module is enabled. Refer to MSCAN section for details.
