Register Definitions
The register definitions are based on the standard IBM
addresses for LPT. All of the standard printer ports are
supported. The additional registers attach to an upper bit
decode
Note 1: These addresses are added to the parallel port base address as selected by configuration register or jumpers.
Note 2: All addresses are qualified with AEN. Refer to the AEN pin definition.

operated in that mode. The port registers vary depending
on the mode field in the ecr. The table below lists these
dependencies. Operation of the devices in modes other
