sequence) may be performed. The status register

may be polled to determine if an error occurs

during the sequence.

to any information or reserved for future use are set

to "0". This command functions independently of

the VPP voltage. RP# must be VIH.

To clear the status register, the Clear Status

Register command (50H) is written. It functions

independently of the applied VPP voltage. RP#

must be VIH. 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.

4.5 Query Command

Query database can be read by writing Query

command (98H). Following the command write,

read cycle from address shown in Table 6 through

Table 10 retrieve the critical information to write,

erase and otherwise control the flash component.

A0 of query offset address is ignored when x8

mode (BYTE# = VIL).

Query data are always presented on the low-byte

data output (DQ0-DQ7). In x16 mode, high-byte

(DQ8-DQ15) outputs 00H. The bytes not assigned

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.
