5.0 PARALLEL PORT
5.1 Printer Interface Logic
The parallel port of the W83977EF/CTF makes possible the attachment of various devices that
accept eight bits of parallel data at standard TTL level. The W83977EF/CTF 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). and 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 5-1 shows the pin definitions for different modes of the parallel port.
