Significance Device Differences Motorola Part No. 33742 Reset Duration 15 ms (typical) Device Differences The duration of the reset mode, in which the RST terminal is asserted low, is 15 ms typical. Reset mode is entered after device power up, when a VDD undervoltage condition occurred and if the watchdog register is not properly triggered. The duration of the reset mode, in which the RST terminal is asserted low, is 3.5 ms typical. Reset mode is entered after device power up, when a VDD undervoltage condition occurred and if the watchdog register is not properly triggered.
