sequence) may be performed. The status register
may be polled to determine if an error occurs
during the sequence.
To clear the status register, the Clear Status
Register command (50H) is written. It functions
independently of the applied V
PP
voltage. RP#
must be V
IH
. This command is not functional during
block erase, full chip erase, (multi) word/byte write,
block lock-bit configuration, block erase suspend or
(multi) word/byte write suspend modes.

command (98H). Following the command write,

Query Command
Query data are always presented on the low-byte
data output (DQ
0
-DQ
7
). In x16 mode, high-byte
(DQ
8
-DQ

) outputs 00H. The bytes not assigned
to any information or reserved for future use are set
to "0". This command functions independently of
the V
PP
voltage. RP# must be V
IH
.

4.5.1 BLOCK STATUS REGISTER
This field provides lock configuration and erase
status for the specified block. These informations
are only available when device is ready (SR.7 = 1).
If block erase or full chip erase operation is finished
irregularly, block erase status bit will be set to "1". If
bit 1 is "1", this block is invalid.
