8. PARALLEL PORT
8.1
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 8-1 (including Table 6-1-1 and 6-1-2) shows the pin definitions for different modes of the parallel
port.
