OPERATION
Repeat for subsequent byte writes.
SR full status check can be done after each byte write, or after
a sequence of byte writes.
Write FFH after the last byte write operation to place the device
into read array mode.
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 an error is detected, clear the Status Register before attempting a
retry or other error recovery operations.
