Appendix A Electrical Characteristics
A.3.1.3
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
Erasing a NVM block takes:
The setup time can be ignored for this operation.
A.3.1.5
The time it takes to perform a blank check on the Flash or EEPROM is dependant on the location of the
