4.8.1 FLASH Block Protect Register
Technical Data

NOTE:
Address:
Due to the ability of the on-board charge pump to erase and program the
FLASH memory in the target application, provision is made to protect
blocks of memory from unintentional erase or program operations due to
system malfunction. This protection is done by use of a FLASH block
protect register (FLBPR). The FLBPR determines the range of the
FLASH memory which is to be protected. The range of the protected
area starts from a location defined by FLBPR and ends to the bottom of
the FLASH memory ($FFFF). When the memory is protected, the HVEN
bit cannot be set in either ERASE or PROGRAM operations.
When the FLBPR is cleared (all 0’s), the entire FLASH memory is
protected from being programmed and erased. When all the bits are set,
the entire FLASH memory is accessible for program and erase.
The FLASH block protect register is implemented as an 8-bit I/O register.
The content of this register determine the starting location of the
protected range within the FLASH memory.
