Read Status Register 1 (RDSR1 05h)

The Read Status Register 1 (RDSR1) command allows the Status Register 1 contents to be read from SO.

The volatile version of Status Register 1 (SR1V) contents may be read at any time, even while a program,

erase, or write operation is in progress. It is possible to read 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.

Figure 10.6 Read Status Register 1 (RDSR1) Command Sequence

This command is also supported in QPI Mode. In QPI Mode the instruction is shifted in on IO0-IO3 and the

returning data is shifted out on IO0-IO3, two clock cycles per byte.

10.3.2

Read Status Register 2 (RDSR2 07h)

The Read Status Register 2 (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.

In QPI Mode, Status Register 2 may be read via the Read Any Register command, see Read Any Register

(RDAR 65h) on page 101
