Abstract

This idea relates to a high density and versatile counter/timer having 16-bit registers. The versatility of the counter/timer is achieved by (1) individually programming each input line to operate in a different mode, (2) programmably selectable interrupt modes, (3) individually presetting each register to a desired value, and (4) the presence of an oscillator clock source which can be programmably selected for use as the input to any of the 16 registers.
