Read Status Register (RDSR) (05h)
The Read Status Register (RDSR) instruction 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 recommended to check the Write In Progress
(WIP) bit before sending a new instruction to the device. It is also possible to read the Status Register
continuously, as shown in Figure 9.
The instruction sequence is shown in Figure 9.1 while using the Enable Quad I/O (EQIO) (38h) command.
