Notes:
When Erase processing is suspended and resumed, this is not considered as an additional erase with
respect to the specified Flash erase endurance.
The suspend / resume mechanism cannot be nested. Therefore, the following sequence is not allowed:
Erase Flash ► Suspend ► Start another erase flash ► Suspend.
