8.0 Legacy Functional Blocks
8.2 PARALLEL PORT
8.2.1
The Parallel Port supports all IEEE1284 standard communication modes: Compatibility (known also as Standard or SPP),
Bidirectional (known also as PS/2), FIFO, EPP (known also as Mode 4) and ECP (with an optional Extended ECP mode).
8.2.2
The Parallel Port functional block register maps are grouped according to first and second level offsets. EPP and second
level offset registers are available only when base address is 8-byte aligned.
