2.6.3 FLASH Mass Erase Operation
Use the following procedure to erase the entire FLASH memory to read as a 1:
A mass erase will erase the internal oscillator trim value at $FFC0.

Mass erase is disabled whenever any block is protected (FLBPR does not
equal $FF).
Programming and erasing of FLASH locations cannot be performed by
code being executed from the FLASH memory. While these operations
must be performed in the order as shown, other unrelated operations may
occur between the steps.
