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 block erase or after a sequence of block erases.
Write FFH (or FFFFH) after the last block erase operation to reset the device(s) to ready array mode.
If a block erase operation fails due to a low V
PP
(setting SR Bit 3), the Clear Status Register command
must
be issued
before further attempts are allowed by the Write State Machine.
If a block erase operation fails during a multiple block erase sequence, SR Bit 4 (Write Status) will not be cleared until the
Command User Interface receives the Clear Status Register command.
