Port E reduced drive—Select reduced drive for output port
This bit configures the drive strength of all associated port output pins as either full or reduced. If a pin is used as
input this bit has no effect. The reduced drive function is independent of which function is being used on a particular
pin.
1 Reduced drive selected (approx. 1/5 of the full drive strength)
0 Full drive strength enabled
Port B reduced drive—Select reduced drive for output port
This bit configures the drive strength of all associated port output pins as either full or reduced. If a pin is used as
input this bit has no effect. The reduced drive function is independent of which function is being used on a particular
pin.
1 Reduced drive selected (approx. 1/5 of the full drive strength)
0 Full drive strength enabled
