OPERATION
Repeat for subsequent block erasures.
Full status check can be done after each block erase
or after a sequence of block erasures.
Write FFH after the last operation to place the device
into read array mode.
CSR.5, SR.4, SR.3, and SR.1 are only cleared by the Clear Status
Register Command in cases where multiple blocks are erased
before full status is checked.
If an error is detected, clear the Status Register before attempting a
retry or other error recovery operations.
