Appendix A Electrical Characteristics
A.4.1.4
Erasing a NVM block takes:
The setup times can be ignored for this operation.
A.4.1.5
The time it takes to perform a blank check on the Flash is dependant on the location of the first non-blank
word starting at relative address zero. It takes one bus cycle per word to verify plus a setup of the command.
