Hi,

I've been trying to use this MPLAB thing with a 12C508/JW (the UV erasable
one) and can't get it to program the "MOVLW 0x30" into location 0x1ff.
My program has an
        org     0x1ff
        movlw   0x30
at the end, and even when I specify programming calibration memory it
still comes out as XORLW 0xFF.

Also, when I try to use __idlocs this enters data at addresses 0x1ff,
0x200, 0x201 and 0x202 which obviously can't be right (although I don't
know where they should go).

This is using MPLAB 3.12 which internally uses MPASM(WIN) 01.40.

Any help?
Frank
