A.3.1.3 Sector Erase
Erasing a 1024-byte Flash sector or a 4-byte EEPROM sector takes:
The setup time can be ignored for this operation.
A.3.1.4 Mass Erase
Erasing a NVM block takes:
The setup time can be ignored for this operation.
A.3.1.5 Blank Check
The time it takes to perform a blank check on the Flash or EEPROM 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.
