12. PARALLEL PORT
12.1 Printer Interface Logic
The W83627DHG parallel port can be attached to devices that accept eight bits of parallel data at
standard TTL level. The W83627DHG supports the IBM XT/AT compatible parallel port (SPP), the
bi-directional parallel port (BPP), the Enhanced Parallel Port (EPP), and the Extended Capabilities
Parallel Port (ECP) on the parallel port.
The following tables show the pin definitions for different modes of the parallel port.
