Register Access Commands
Read Status Register-1 (RDSR1 05h)
Read Status Register-2 (RDSR2 07h)
The Read Status Register-1 (RDSR1) command allows the Status Register-1 contents to be read from SO.
The Status Register-1 contents may be read at any time, even while a program, erase, or write operation is in
progress. It is possible to read the Status Register-1 continuously by providing multiples of eight clock cycles.
The status is updated for each eight cycle read. The maximum clock frequency for the RDSR1 (05h)
command is 133 MHz.
The Read Status Register (RDSR2) command allows the Status Register-2 contents to be read from SO. The
Status Register-2 contents may be read at any time, even while a program, erase, or write operation is in
progress. It is possible to read the Status Register-2 continuously by providing multiples of eight clock cycles.
The status is updated for each eight cycle read. The maximum clock frequency for the RDSR2 command is
133 MHz.
