... Functional Description A microprocessor’s (µP’s) reset input starts the µ known state. The APX809/810 assert reset to prevent code-execution errors during power-up, power-down, or brownout conditions. They assert a reset signal whenever the V declines below a preset threshold, keeping it asserted for at least 240ms after V has risen above the reset threshold ...
