Repeat for subsequent data writes.
In addition, the card’s ready-busy status register or the RDY/BSY# pin may be used.
Full device-level status check can be done after each data write or after a sequence of data writes.
Write FFH (or FFFFH) after the last data write operation to reset the device(s) to read array mode.
If a data write operation fails due to a low V
(setting SR Bit 3), the Clear Status Register command
must
be issued
before further attempts are allowed by the Write State Machine.
If a data write operation fails during a multiple write sequence, SR Bit 4 (Write Status) will not be cleared until the
Command User Interface receives the Clear Status Register command.
