Clear Status Register
The Clear Status Register command clears the status register and functions independent of V
The Write State Machine sets and clears status bits (SR[7:6,2,0]), but it only sets error bits
(SR[5:4,3,1]). The Status Register should be cleared before starting a command sequence to avoid
any ambiguity. A device reset also clears the Status Register.
Read Device Identifier
The Read Device Identifier command instructs the device to output Manufacturer/ Device
Identifier codes, block-lock status, Protection Register data, and Configuration Register data when
read. (See
Identifier command.)
