EPP Mode Data Transfer Cycle
1. Program executes an I/O write cycle to EPP Data
Port-4.
2. The -Write line is asserted and the data is output to
the parallel port.
3. The -DataStb is asserted, since -Write is asserted
low.
4. The port waits for the acknowledge from the periph-
eral, -Write deasserted.
5. The -DataStr is deasserted and EPP cycle ends.
6. -Write is asserted low to indicate that the next cycle
may begin.
