EPP Address. This register is equivalent to and operates in the same manner as the

 

 

 

EPP Address Register in a standard host-side parallel port controller chip. The

 

 

 

register is writable when Auto Mode is 0 and the Mode field in the Extended Control

 

 

 

Register is set to 100. A write to this register initiates an EPP address write transfer

 

 

 

on the parallel port. The register is always readable. When the Mode is set to 100, a

 

 

 

read access will initiate an EPP address read transfer on the parallel port, and the

 

 

 

value returned will be the address value read from the peripheral. Reads when not in

 

 

 

Mode 100 will return whatever value has been previously latched, but will not have

 

 

 

any effect on the parallel port.

EPP Data. This register is equivalent to and operates in the same manner as the EPP

 

 

 

Data Register in a standard host-side parallel port controller chip. The register is writ-

 

 

 

able when Auto Mode is 0 and the Mode field in the Extended Control Register is set

 

 

 

to 100. A write to this register initiates an EPP data write transfer on the parallel port.

 

 

 

The register is always readable. When the Mode is set to 100, a read access will

 

 

 

initiate an EPP data read transfer on the parallel port, and the value returned will be

 

 

 

the data value read from the peripheral. Reads, when not in Mode 100, will return
