Reset
This register configures the output pins as wired-OR. If enabled the output is driven active low only
(open-drain). A logic level of “1” is not driven. It applies also to the SPI and SCI outputs and allows
a multipoint connection of several serial modules. These bits have no influence on pins used as
inputs.
Field
24.0.5.26 Port M Data Register (PTM)
Read: Anytime.
Write: Anytime.
Port M pins 7–0 are associated with the CAN0, 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.

0 Output buffers operate as push-pull outputs.
1 Output buffers operate as open-drain outputs.
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 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.
