nPORRST
t_f(nPORRST)
Filter time nPORRST pin;
pulses less than MIN will be filtered out, pulses greater than
MAX will generate a reset⁽¹⁾

2000 ns
nRST
t_f(nRST)
Filter time nRST pin;
pulses less than MIN will be filtered out, pulses greater than
MAX will generate a reset
475
2000 ns
TEST
t_f(TEST)
Filter time TEST pin;
pulses less than MIN will be filtered out, pulses greater than
MAX will pass through
475
2000 ns
(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, and so forth) without also generating a valid reset signal to the CPU.
