6. PARALLEL PORT
6.1 Printer Interface Logic
The parallel port of the W83627SF makes possible the attachment of various devices that accept eight
bits of parallel data at standard TTL level. The W83627SF supports an IBM XT/AT compatible parallel
port (SPP), bi-directional parallel port (BPP), Enhanced Parallel Port (EPP), Extended Capabilities
Parallel Port (ECP), Extension FDD mode (EXTFDD), Extension 2FDD mode (EXT2FDD) on the parallel
port. Refer to the configuration registers for more information on disabling, power-down, and on selecting
the mode of operation.
Table 6-1 shows the pin definitions for different modes of the parallel port.
