resistor’s value is not critical; 100kΩ is large enough not
to load RESET and small enough to pull RESET to
ground. For applications where RESET must be valid to

due to the pull-up resistor and the RESET output’s
reduction in sinking capability. These devices are not
recommended for applications that require a valid
RESET output below 1V.
