T2.2.2

Hardware Configuration Latchin Time

Hardware Configuration Pins are described

µs

from the Deassertion of RESET (either

in the Pin Description section

soft or hard)

T2.2.3

Hardware Configuration pins transition

to output drivers

RESET pulse width

X1 Clock must be stable for at min. of 1µs

µs

during RESET pulse low time

(1)

It is important to choose pull-up and/or pull-down resistors for each of the hardware configuration pins that provide fast RC time

constants in order to latch-in the proper value prior to the pin transitioning to an output driver.
