Data

Sheet

Notes:

1. PA = Program Address, PD = Program Data, VA = Valid Address for reading status bits.

2. In progress and complete refer to status of program operation.

3. Amax9–A14 are don’t care during command sequence unlock cycles.

4. Addresses are latched on the rising edge of CLK.

5. Either CE# or AVD# is required to go from low to high in between programming command sequences.

6. The Synchronous programming operation is dependent of the Set Device Read Mode bit in the Configuration Register.

The Configuration Register must be set to the Synchronous Read Mode.
