LOCKPRE
Power-On Auto-Read
The device is designed to offer automatic reading of the first page without command and address input sequence during power-on.
An internal voltage detector enables auto-page read functions when Vcc reaches about 1.8V. LOCKPRE pin controls activation of
auto- page read function. Auto-page read function is enabled only when LOCKPRE pin is logic high state
after power-on without latency. Power-On Auto Read mode is available only on 3.3V device(K9F56XXU0C).
