Glitch Filters

A glitch filter is present on the following signals.

Table 4-20. Glitch Filter Timing Specifications

Parameter

MIN

MAX

Unit

nPORRST

tf(nPORRST)

500

2000

Filter time nPORRST pin;

pulses less than MIN will be filtered out, pulses greater than

MAX will generate a reset(1)

nRST

tf(nRST)

500

2000

Filter time nRST pin;

pulses less than MIN will be filtered out, pulses greater than

MAX will generate a reset

TEST

tf(TEST)

500

2000

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.
