22.3.2.35 Port M Polarity Select Register (PPSM)
Read: Anytime.
Write: Anytime.
This register selects whether a pull-down or a pull-up device is connected to the pin. If CAN is active a
pull-up device can be activated on the RXCAN[3:0] inputs, but not a pull-down.
22.3.2.36 Port M Wired-OR Mode Register (WOMM)
Read: Anytime.
Write: Anytime.
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 CAN outputs and allows a multipoint
connection of several serial modules. This bit has no influence on pins used as inputs.
