WRITE OPERSTION STATUS

The device provides several bits to determine the sta-

tus of a write operation: Q5, Q6, Q7. Table 10 and the

following subsections describe the functions of these bits.

Q7, and Q6 each offer a method for determining whether

a program or erase operation is complete or in progress.

These three bits are discussed first.
