Description



The ST78C36/36A is a monolithic Parallel Port Interface for use with IBM PC compatible platforms. 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 ST78C36 that ay be accessed by programmed I/O or DMA cycles.
