tf(TEST)
Filter time TEST pin;
pulses less than MIN will be filtered out, pulses greater than
MAX will pass through
(1) The glitch filter design on the nPORRST signal is designed such that no size pulse will reset any part of the microcontroller (flash pump,
I/O pins, etc.) without also generating a valid reset signal to the CPU.
