3.13.1 Mass Erase Timing
The time required to erase the entire NVM array (both program and data) is calculated using the formula:
The setup time can be ignored for this operation.
3.13.2 Blank Check Timing
The time it takes to perform a blank check on the program or data Flash is dependant on the location of the
first non-blank word, starting from relative address zero. One f
