Note:
Inputs may or may not be recognized at this time. Caution should be taken to keep E high as V
rises past V
(min). Some systems
may perform inadvertent write cycles after V
rises above V
(min) but before normal system operations begin. Even though a power on
reset is being applied to the processor, a reset condition may not occur until afterthe system clock is running.
