The setup time can be ignored for this operation.
A.2.1.4 Mass Erase
Erasing a NVM block takes:
The setup time can be ignored for this operation.
A.2.1.5 Blank Check
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.

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. Minimum Erase times are achieved under maximum NVM operating frequency f
5. Minimum time, if first word in the array is not blank
6. Maximum time to complete check on an erased block
