NTE3882 Integrated Circuit NMOS, Counter Timer Control (CTC) Description: The NTE3882 Counter Timer Circuit (CTC) is a programmable, four channel device in a 28–Lead DIP type package that provides counting and timing functions for the NTE3880. The NTE3880 configures the NTE3882’s four independent channels to operate under various modes and conditions as required. The internal structure of the NTE3882 consists of an NTE3880 bus interface, internal control logic, four counter channels, and interrupt control logic. Each channel has an interrupt vector for automatic interrupt vectoring, and interrupt priority is determined by channel number with channel ∅ having the highest priority. The channel logic is composed of 2 registers, 2 counters and control logic.
