SR.4, SR.3 and SR.1 are only cleared by the Clear Status
Register command in cases where multiple locations are
written before full status is checked.
If error is detected, clear the status register before attempting
retry or other error recovery.
Repeat for subsequent word/byte writes.
SR full status check can be done after each word/byte write
or after a sequence of word/byte writes.
Write FFH after the last word/byte write operation to place
device in read array mode.
