Status-Check Sequence
NOTE:
1. Sequence may be repeated to erase additional blocks.
2. Complete status check is not required. However, if SR3 = 1, further ERASEs are inhibited until the status register is
cleared.
3. To return to the array read mode, the FFh command must be issued.
4. Refer to the ERASE SUSPEND flowchart for more information.
5. If SR3 is set during a WRITE or BLOCK ERASE attempt, CLEAR STATUS REGISTER must be issued before further WRITE or
ERASE operations are allowed by the CEL.
6. Status register bits 3-5 must be cleared using CLEAR STATUS REGISTER.

of this specification is not implied. Exposure to abso-
lute maximum rating conditions for extended periods
may affect reliability.
