2. Complete status check is not required. However, if SR3 = 1, further WRITEs are inhibited until the status register
3. Device will be in status register read mode. To return to the array read mode, the FFh command must be issued.
4. If SR3 is set during a WRITE or BLOCK ERASE attempt, CLEAR STATUS REGISTER must be issued before further
5. Status register bits 3-5 must be cleared using CLEAR STATUS REGISTER.
