7.4. Read Status Register (RDSR) (05H or 35H or 15H)

The Read Status Register (RDSR) command is for reading the Status Register. 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 command to the device. It is

also possible to read the Status Register continuously.

For command code “05H” / “35H”, the SO will output Status

The command code “15H” only supports the QPI mode, the I/O0 will output Status Register

S1-S0. (For 120MHz Frequency, the 15H will better than 05H to check the WIP bit)
