Table 35: Block Status Register<br />
Notes:<br />
1. BA = Block Address beginning location (for example, 08000h is the block 1 beginning location when the block size is 32Kword).<br />
B.4 CFI Query Identification String<br />
.<br />
Offset Length Description Add. Value<br />
1 Block Lock Status Register BA+2 --00 or --01<br />
BSR.0 Block lock status<br />
0 = Unlocked<br />
1 = Locked<br />
BA+2 (bit 0): 0 or 1<br />
BSR.1 Block lock-down status<br />
0 = Not locked down<br />
1 = Locked down<br />
BA+2 (bit 1): 0 or 1<br />
BSR 2–7: Reserved for future use BA+2 (bit 2–7): 0<br />

The Identification String verifies that the component supports the Common <strong>Flash</strong><br />
Interface specification. It also indicates the specification version and supported vendorspecified<br />
command set(s).<br />
