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.
Conditions are shown in Table A-4 unless otherwise noted
Num C
NOTES:
1. Restrictions for oscillator in crystal mode apply!
2. Minimum Programming times are achieved under maximum NVM operating frequency f
3. Maximum Erase and Programming times are achieved under particular combinations of f
4. Row Programming operations are not applicable to EEPROM
5. Minimum Erase times are achieved under maximum NVM operating frequency f
6. Minimum time, if first word in the array is not blank
7. Maximum time to complete check on an erased block
