PIC18F97J60 datasheet header file mismatch

[Szőgyényi Gábor]

In the datasheet of PIC18F97J60 the config words located at:

300000h    CONFIG1L
300001h    CONFIG1H
300002h    CONFIG2L
300003h    CONFIG2H
300004h    CONFIG3L
300005h    CONFIG3H
3FFFFEh   DEVID1
3FFFFFh   DEVID2

but in the header files defined :

#define __CONFIG1L     0x01FFF8
#define __CONFIG1H     0x01FFF9
#define __CONFIG2L     0x01FFFA
#define __CONFIG2H     0x01FFFB
#define __CONFIG3L     0x01FFFC
#define __CONFIG3H     0x01FFFD

Which is relevant?
Can someone give me a really working CONFIG setting for PIC18F97J60?
The -mpic14 style CONFIG definitions are not working on -mpic16, because the header files has differencies.

Hi,

Have you tried using the new (although a few years old) pragma style?

Example taken from section 4.6.17 on the SDCC manual. It will most surely need changes for your PIC:

#pragma config CP0=OFF,OSCS=ON,OSC=LP,BOR=ON,BORV=25,WDT=ON,WDTPS=128,CCP2MUX=ON
#pragma config STVR=ON

That information is passed to GPUTILS, which knows about all those options (see https://sourceforge.net/p/gputils/code/HEAD/tree/trunk/gputils/header/p18f97j60.inc#l2281), so it should work even if the SDCC header is wrong (we should fix it by the way).

Cheers,
Diego

Thanks.

When I am using this "#pragma config" style configuration, the PICkit 2 programmer gives error at flashing the output HEX file.

Program Memory Errors

Address Good Bad
01FFFE 00FFFF 00F000

Maybe the compiler places the config word to a bad memory address?

[Raphael Neider]

Somewhere in the (non-free) include/pic16 directory, there should be a file pic16devices.txt which lists (among other things) the addresses of the configuration words... Or was that for pic14?
If such a file exists, you can try fixing the addresses in there for the relevant (family) record.
If I can manage, I'll try and post more useful instructions.

[Szőgyényi Gábor]

Yes, the file exists and there is information for the PIC18F97J60.

name        18f97j60
using       18f67j10
ramsize     4096
configword  0x01FFFC 0xF8 0xF8
configword  0x01FFFD 0x07 0xF7

But I don't know it is correct or not.

[Maarten Brock]

Is this header file generated or hand written? I believe most headers are generated from .INC files from microchip and in that case the problem should be fixed upstream.

[Szőgyényi Gábor]

I don't know is this file generated or not. I think we need to open an issue to check and fix all the devices in this pic16devices.txt file.
