The APS Port bus (APS[4:0]) is a bi-directional control bus that
can be used to implement a 1+1 APS system. When the
APSPOE register bit is set low, the APS[4:0] bus is an input.
Data on this bus is used by TPOP to generate the path RDI and
path FEBE. When the APSPOE register bit is set high, the
APS[4:0] bus is an output with data generated by RPOP.
