Debounced manual pushbutton reset input.

Watchdog time delay selection. (tTD = 150ms for TD = GND, tTD = 610ms for

TD=Open, and tTD = 1200ms for TD = VCC).

Selects 10% (TOL connected to GND) or 20% (TOL connected to VCC) trip point

tolerance.

Ground.

Active HIGH reset output. RESET is active:

1. If VCC falls below the reset voltage trip point.

2. If PBRST is LOW.

3. If ST is not strobed LOW before the timeout period set by TD expires.

4. During power-up.

Active LOW reset output. (See RESET).

Strobe input.

3.3V power.
