READ STATUS REGISTER

The READ STATUS REGISTER command allows the status register to be read. The status

register may be read at any time, even while a PROGRAM, ERASE, or WRITE STATUS

REGISTER cycle is in progress. When one of these cycles is in progress, it is recommen-

ded to check the write in progress (WIP) bit before sending a new command to the de-

vice. It is also possible to read the status register continuously.
