NOTES:
1. All voltages referenced to ground.
2. Measured with outputs open and ST and PBRST within 0.5V of supply rails.
3. PBRST is internally pulled up to V CC with an internal impedance of 40k typical.
4. t R = 5 μ s.
5. RST is an open-drain output.
6. Must not exceed t TD minimum. See Table 1.
7. RST remains within 0.5V of V CC on power-down until V CC drops below 2.0V. RST remains within
0.5V of GND on power-down until V CC drops below 2.0V.
8. Measured with outputs open and ST and PBRST at TTL levels.
9. Watchdog can not be disabled. It must be strobed to avoid resets.
