• Manufacturer: Macronix

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 10 and the following subsections describe the func-
tions of these bits. Q7, RY/BY, and Q6 each offer a
method for determining whether a program or erase op-
Notes:
1. Performing successive read operations from the erase-suspended sector will cause Q2 to toggle.
1. Performing successive read operations from any address will cause Q6 to toggle.
3. Reading the byte address being programmed while in the erase-suspend program mode will indicate logic "1" at the Q2 bit.
