NOTES:
1. All timing is shown with respect to 20% V
2. RESET is recognized during the first clock cycle it is held low. Internal circuitry then drives the pin low for four
3. PW
NOTES:
1. Rising edge sensitive input.
2. Falling edge sensitive input.
3. Maximum pulse accumulator clocking rate is E-clock frequency divided by 2.
clock cycles, releases the pin, and samples the pin level two cycles later to determine the source of the interrupt.
