Notes: 1. PBRST is internally pulled HIGH to V_CCthrough a nominal 40kΩ resistor.

2. RESET is an open drain output.

3. RESET remains within 0.5V of V_CCon power-down until V_CCfalls below 2V. RESET remains within 0.5V of ground on power-down

until V_CCfalls below 2.0V.

4. Must not exceed the minimum watchdog time-out period (t_TD). The watchdog circuit cannot be disabled. To avoid a reset, ST must be

strobed.
