1. Read: Anytime. In emulation modes, read operations will return the data from the external bus, in all other modes the data source
2. Reset values in emulation modes are identical to those of the target mode.

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