NOTES:
1. All voltages referenced to ground.
2. PBRST is internally pulled up to VCC with an internal impedance of 40 kΩ=typical.
3. Measured with VCC ≥ 2.7V.
4. Measured with VCC < 2.7V.
5. Measured with outputs open, VCC ≤ 3.6 volts, and all inputs at VCC or Ground.
6. Must not exceed tTD minimum.
7. The Watchdog cannot be disabled it must be strobed to avoid resets.
8. Noise immunity - Pulses < 2 µs at VCCTP minimum will not cause a reset.
9. tR = 5 µs.
