Check (optional)
Complete Status
2. Complete status check is not required. However, if SR3 = 1, further ERASEs are inhibited until the status register
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
6. Status register bits 3-5 must be cleared using CLEAR STATUS REGISTER.
