B.5.1.3 Sector Erase
Erasing either a 512 byte or 1024 byte Flash sector takes:
The setup times can be ignored for this operation.
B.5.1.4 Mass Erase
Erasing a NVM block takes:
This is independent of sector size.
The setup times can be ignored for this operation.
Conditions are shown in Table A-4 unless otherwise noted
