2. Status register bit 6 is “1” when the cache is ready to accept new data. R/B# follows bit 6.
3. Status register bit 7 typically mirrors the status of WP#. However, when BLOCK LOCK is

used, this bit will be “1” when all internal operations are complete.

used, status register bit 7 returns “0” if PROGRAM or ERASE operations are performed on
a locked block. Additionally, when using the OTP PROGRAM DATA command, status regis-
ter bit 7 returns “0” if the page is protected. This bit is not modified until the next PRO-
GRAM or ERASE command is issued.
