NEe Microcomputers, Inc. PROGRAMMABLE INTERVAL TIMER NEe p.PD8253 p.PD8253-5 DESCR IPTION The NEC flPD8253-5 contains three independent, programmable, multi-modal 16-bit counter/timers. It is designed as a general purpose device, fully compatible with the 8080 family. The flPD8253-5 interfaces directly to the busses of the processor as an array of I/O ports. The flPD8253-5 can generate accurate time delays und~r the control of system software. The three independent 16-bit counters can be clocked at rates from DC to 4 MHz. The system software controls the loading and starting of the counters to provide accurate multiple time delays. The counter output flags the processor at the completion of the time-out cycles.
