6.2 Read STATUS Register
(RDSR
)
The Read STATUS Register (
RDSR
) instruction provides access to the
STATUS register. The ready/busy and write enable status of the device can be determined
by the RDSR
instruction. Similarly, the Block Write-Protect (BP1, BP0)
bits indicate the extent of memory array protection employed. The STATUS register is
read by asserting the CS pin, followed by sending in a 05h
opcode on the SI pin. Upon completion of the opcode, the device will return the 8‑bit
STATUS register value on the SO pin.
