Read Status Register
The status register is 8 bits wide. The status register contains information pertaining to the current
condition of the flash device and its partitions. To determine a partition
s status, execute the Read
Status Register command. To read status register data, execute a signal-word asynchronous read. A
status register bit is considered set if its value is a one (1) and cleared if its value is a zero (0).
Status register data is output on DQ

outputs 00h. Each partition has its own status
register data. Information contained in this register can only be accessed by executing a single-
word asynchronous read.
