Read: Anytime. Write: Anytime.
This register selects whether a port M output is configured as push-pull or wired-or. When a Wired-OR
Mode Register bit is set to 1, the corresponding output pin is driven active low only (open drain) and a
high level is not driven. A Wired-OR Mode Register bit has no effect if the corresponding pin is configured
as an input.
These bits apply also to the CAN transmitter and allow a multipoint connection of several serial modules.
