Figure 9.5
Write Disable (WRDI) Command Sequence
9.6
Read Status Register (RDSR)
The Read Status Register (RDSR) command outputs the state of the Status Register bits.
Table 9.2
shows
the status register bits and their functions.
The RDSR command may be written at any time, even while a program, erase, or Write Status Register
operation is in progress. The host system should check the Write In Progress (WIP) bit before sending a new
command to the device if an operation is already in progress.
Figure 9.6
shows the RDSR command
sequence, which also shows that it is possible to read the Status Register continuously until CS# is driven
high.
