23.0.5.12 S12X_EBI Ports Reduced Drive Register (RDRIV)
Read: Anytime. In emulation modes, read operations will return the data from the external bus, in
all other modes the data source is depending on the data direction value.
Write: Anytime. In emulation modes, write operations will also be directed to the external bus.
This register is used to select reduced drive for the pins associated with ports A, B, E, and K. If
enabled, the pins drive at about 1/6 of the full drive strength. The reduced drive function is
independent of which function is being used on a particular pin.
The reduced drive functionality does not take effect on the pins in emulation modes.
