NOTES:
1. RESET is recognized during the first clock cycle it is held low. Internal circuitry then drives the pin low for four
clock cycles, releases the pin, and samples the pin level two cycles later to determine the source of the interrupt.
Refer to 9 RESETS, INTERRUPTS, AND LOW POWER MODES for further detail.
2. All timing is shown with respect to 20% VDD and 70% VDD, unless otherwise noted.
Table A-4 Control Timing
VDD = 5.0 Vdc ± 10%, VSS = 0 Vdc, TA = TL to TH
