NOTES:
1. RESET is recognized during the first clock cycle it is held low. Internal circuitry then drives the pin low for four
2. All timing is shown with respect to 20% V
1. Rising edge sensitive input
2. Falling edge sensitive input
3. Maximum pulse accumulator clocking rate is E-clock frequency divided by 2.
