What is the operation of the ER pin when it is at 'H' while the reset output is at 'H' and 'L', respectively, for fixed delay time (built-in counter timer) reset ICs?
When the reset output is at 'H' the output is forced to 'L' when the ER pin is at 'H'. When the reset output is at 'L' the output remains at 'L' even if the ER pin is set to 'H'.
