1. Read: Anytime. In emulation modes, read operations will return the data from the external bus, in all other modes the data source
Chapter 2 Port Integration Module (S12XEPIMV1)
2.3.14
This register is used to select reduced drive for the pins associated with the S12X_EBI ports A, B, C, D,
E, and K. If enabled, the pins drive at approx. 1/5 of the full drive strength.
The reduced drive functionality does not take effect on the pins in emulation modes.

is depending on the data direction value.
Write: Anytime. In emulation modes, write operations will also be directed to the external bus.

Port K reduced drive—Select reduced drive for outputs
This bit configures the drive strength of all Port K 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.
Reserved—
Port E reduced drive—Select reduced drive for outputs
This bit configures the drive strength of all Port E 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 D 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 C 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.
