10.5 Clear Status Register<br />
Numonyx <strong>Wireless</strong> <strong>Flash</strong> <strong>Memory</strong> (<strong>W30</strong>) (<strong>W30</strong>)<br />
The Clear Status Register command clears the status register and leaves all partition<br />
output states unchanged. The WSM can set all status register bits and clear bits<br />
SR[7:6,2,0]. Because bits SR[5,4,3,1] indicate various error conditions, they can be<br />
cleared only by the Clear Status Register command. By allowing system software to<br />
reset these bits, several operations (such as cumulatively programming several<br />
addresses or erasing multiple blocks in sequence) can be performed before reading the<br />
status register to determine whether an error occurred.<br />
If an error is detected, the Status Register must be cleared before beginning another<br />
command or sequence. <strong>Flash</strong> device reset (RST# = V IL ) also clears the status register.<br />
This command functions independently of V PP .<br />
