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