Clear Status Register
The Clear Status Register command clears the status register and leaves all partition
output states unchanged. The WSM can set all status register bits and clear bits
SR[7:6,2,0]. Because bits SR[5,4,3,1] indicate various error conditions, they can be
cleared only by the Clear Status Register command. By allowing system software to
reset these bits, several operations (such as cumulatively programming several
addresses or erasing multiple blocks in sequence) can be performed before reading the
status register to determine whether an error occurred.
If an error is detected, the Status Register must be cleared before beginning another
command or sequence. Flash device reset (RST# = V
