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 7.
