NOTE:
NOTE:
While these operations must be performed in the order shown, other
unrelated operations may occur between the steps.
Use this step-by-step procedure to erase entire FLASH memory to read
as logic 1:
* When in Monitor mode, with security sequence failed
block protect register instead of any FLASH address.
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 shown, other unrelated operations may
occur between the steps.
