Flash Block Protect

[Jackson]

Hi,
Could someone say how can I protect Block3 flash to write in PIC18F452?(address 0x6000-0x7FFF).
Thanks.

In 16F series there was keywords like PROTECT_5\% and others. Maybe these settings are completely missing in 18F series.
Maybe there is a much simpler way but you can try the following:
Open the HEX file after compiling.
Find the following two lines:
:020000040030CA // this line sets the offset address to 0x300000
:0E00000000210C0F000181000FC000E00F4036 //config bytes
-------------------------!!------------
The two digits signed by "!" is the CONFIG5L (0x300008). Modify it to "07" to protect 0x6000-0x7FFF:
:0E00000000210C0F0001810007C000E00F4036
