Chapter 2 Port Integration Module (S12XEPIMV1)
This register configures the re-routing of SCI3, IIC0, CS[3:0] on alternative ports.
2.4
2.4.1
Each pin except PE0, PE1, and BKGD can act as general purpose I/O. In addition each pin can act as an
output from the external bus interface module or a peripheral module or an input to the external bus
interface module or a peripheral module.
2.4.2
A set of configuration registers is common to all ports with exceptions in the expanded bus interface and
ATD ports
not become active.
This device does not become active while the port is used as a push-pull output.
