WRITE OPERATION STATUS

The device provides several bits to determine the status of a write operation: Q2, Q3, Q5, Q6, Q7, and RY/BY.Table B and the following subsections describe the functions of these bits. Q7, RY/BY, 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.

Table B. Write Operation Status

Notes:

1.Performing successive read operations from the erase-suspended sector will cause Q2 to toggle. 2.Performing successive read operations from any address will cause Q6 to toggle.

3.Reading the byte/word address being programmed while in the erase-suspend program mode will indicate logic "1" at the Q2 bit.

However, successive reads from the erase-suspended sector will cause Q2 to toggle.
