READ STATUS REGISTER
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.
