Notes:
1. Not 100% tested.
2. See the “Erase and Programming Performance” section for more information.
3. If a program suspend command is issued within tPOLL, the device requires tPOLL before reading status data, once
programming has resumed (that is, the program resume command has been written). If the suspend command was issued
after tPOLL, status data is available immediately after programming has resumed. See Figure 22.
