stead of any FLASH address.
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.
A mass erase will erase the internal oscillator trim value at $FFC0.
