Notes
1. Check SR.7 to determine block erase, program, or lock-bit configuration completion. SR.6-SR.0 are not driven
2. If both SR.5 and SR.4 are "1" after a block erase or lock-bit configuration attempt, an improper command se-
3. SR.3 does not provide a continuous programming voltage level indication. The WSM interrogates and indicates the
4. SR.1 does not provide a continuous indication of block lock-bit values. The WSM interrogates the block lock-bits
5. SR.0 is reserved for future use and should be masked when polling the status register.
Notes:
1. After a Buffer-Write command, XSR.7 = 1 indicates that a Write Buffer is available.
2. XSR.6-XSR.0 are reserved for future use and should be masked when polling the status register.
