Operation as a standard Centronics printer port is the default, but software may re-configure the device to support bi-directional IBM PS/2 parallel port, Enhanced Parallel Port (EPP), or the Extended Capabilities Port (ECP, as defined by Hewlett Packard and Microsoft) modes. The ECP modes are supported by a 16 byte FIFO that may be accessed by programmed I/O or DMA cycles. APPLICATIONS • Printers, Scanners and other peripherals • ZIP Drives and back up drives • Printer Server • Embedded Applications FEATURES • IBM AT bus compatible • Bi-directional port capability • 16 byte FIFO for ECP modes • On-chip oscillator (ST78C36A, ST78C36Q64) • Software selectable Interrupt (5, 7, or 9) and 8-bit DMA channel (ST78C36CQ64) FIGURE 1.
