PIC18F26J50 WPFP

Posted: Mon Nov 08, 2010 1:42 pm

How can I configure the WPFP besides just using WPFP or NOWPFP? I only want to write protect the beginning blocks of flash. I am using the following code to allocate a flash location for reading and writing parameters:

Code:

#org flash, 0xA3FF {}
#rom flash = {settings}

Assuming all executable code is located before this location, how do I protect all flash before this?

Like (just example - doesn't work):

Code:

WPEND
WPFP 39
or
WPFP 0x27

Thanks,

-Matt
