When any EPP data port is accessed, the contents of DB0-DB7 are buffered (non-inverting) and output
to ports PD0-PD7 during a write operation. The leading edge of IOW# causes an EPP data write cycle
to be performed, and the trailing edge of IOW# latches the data for the duration of the EPP write cycle.
During a read operation, ports PD0-PD7 are read, and the leading edge of IOR# causes an EPP read
cycle to be performed and the data to be output to the host CPU.
