During power-up, the CP2400/1/2/3 is held in the reset state until V

the Electrical Characteristics of the power-on reset circuit.
8.3.
The RST pin provides a means for external circuitry to force the CP2400/1/2/3 into a reset state. Asserting RST for
at least T
driver or add an external pull-up resistor to avoid erroneous noise-induced resets. The CP2400/1/2/3 will exit the
reset state and generate a Reset Complete Interrupt approximately one T
detected on RST. Refer to Table 3.3 on page 16 for the Electrical Characteristics.
