Writer Mode Transition Time: Commands cannot be accepted during the oscillation settling
period or the writer mode setup period. After the writer mode setup time, a transition is made to
memory read mode.

2. Auto-programming should be performed once only on the same address block.
For other chips for which the erasure history is unknown, it is recommended that auto-
erasing be executed to check and supplement the initialization (erase) level.
