Notes:
1. SADD = sector address (for Sector Erase), VA = Valid Address for reading status data (see “Flash Write Operation Status”.
2. These waveforms are for the word mode.
3. CE#f refers to active flash device being addressed (either CE#f1 or CE#f2). The chip enable input of the inactive flash device must
be held high during this operation.
