Port M data direction—
This bit determines whether the associated pin is a general-purpose input or output.
1 Associated pin configured as output
0 Associated pin configured as input
Port M pull device enable—Enable pull device on input pin or wired-or output pin
This bit controls whether a pull device on the associated port input pin is active. The polarity is selected by the related
polarity select register bit. If a pin is used as output this bit has only effect if used in wired-or mode with a pullup
device.
1 Pull device enabled
0 Pull device disabled
Port M pull device enable—Enable pull device on input pin or wired-or output pin
This bit controls whether a pull device on the associated port input pin is active. The polarity is selected by the related
polarity select register bit. If a pin is used as output this bit has only effect if used in wired-or mode with a pullup
device.
If CAN is active the selection of a pulldown device on the RXCAN input will have no effect.
