Chapter 4 Port Integration Module (PIM9HZ256V2)
4.3.3.5
Read: Anytime. Write: Anytime.
This register configures whether a pull-up or a pull-down device is activated on configured input or
wired-or output pins. If a pin is configured as push-pull output, the corresponding Pull Device Enable
Register bit has no effect.
4.3.3.6
Read: Anytime. Write: Anytime.
The Port M Polarity Select Register selects whether a pull-down or a pull-up device is connected to the
pin. The Port M Polarity Select Register is effective only when the corresponding Data Direction Register
bit is set to 0 (input) and the corresponding Pull Device Enable Register bit is set to 1.
If a CAN module is enabled, a pull-up device can be activated on the receiver pin, and on the transmitter
pin if the corresponding wired-OR mode bit is set. Pull-down devices can not be activated on CAN pins.
