Note:
Inputs may or may not be recognized at this time. Caution should be taken to keep E1 high
or E2 low as VCC rises past VPFD (min). Some systems may perform inadvertent WRITE
cycles after VCC rises above VPFD (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 after the system clock is running.
