A look ahead terminal counter and a method for generating a terminal count output signal are disclosed. The counter comprises a plurality of counter registers connected to counter enable circuitry for sequencing the registers at a predetermined counter rate. Terminal count enable circuitry is connected to the counter circuitry, e.g. at the input ports of the counter registers, and is operative to generate a terminal count enable signal when those input ports are at a predetermined state. The terminal count enable signal and clock signal are communicated to an output register operative to generate a terminal count output signal when a clock signal is received during the simultaneous presence of the terminal count enable signal. |
