HD68230 Parallel Interface Timer

HD68230 PitT (Parallel Interface Timer) The HD68230 Parallel Interface/Timer provides versatile double buffered parallel interfaces and an operating system oriented timer to HD68000 systems. The parallel interfaces operate in unidirectional or bidirectional modes, either 8 or 16 bits wide. In the unidirectional modes, an associated data direction register determines whether the port pins are inputs or outputs. In the bidire.
