FLASH Memory (FLASH)
FLASH Block Protect Register
The resultant 16-bit address is used for specifying the start address
of the FLASH memory for block protection. The FLASH is protected
from this start address to the end of FLASH memory, at $FFFF. With
this mechanism, the protect start address can be XX00, XX40, XX80,
or XXC0 (at page boundaries — 64 bytes) within the FLASH memory.
Examples of protect start address:
BPR[7:0]
Start of Address of Protect Range
$00–$60
The entire FLASH memory is protected.

(0110 001x)
$EC40 (1110 1100 0100 0000)
$64 or $65
(0110 010x)
$EC80 (1110 1100 1000 0000)
$68 or $69
(0110 100x)
$ED00 (1110 1101 0000 0000)
and so on...
$DE or $DF
(1101 111x)
$FBC0 (1111 1011 1100 0000)
$FE
(1111 1110)
$FFC0 (1111 1111 1100 0000)
$FF
The entire FLASH memory is not protected.
