ALLDIGITAL will need some adjustments for 18F87J50 family and probably some others.
On this family, ANCON1, ANCON0 are alternate SFR to ADCON0, ADCON1. They share the same address, so you need to set/clear WDTCON.ADSHR to switch between SFRs before writing on... dear Microchip

Section 5.3.5.1, pdf page 82, Shared SFRs & WDTCON

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.

I just knew there would be some Oddball chips somewhere.
And shared SFR addresses, with the select bit in the Watchdog Timer control, definitely qualifies as Oddball.
I've updated the program, and replaced the original .zip in post#1.

Well... thanks to scalerobotics for having bring that PIC in here
Definitely, i'll never understand Microchip... that's a real oddball indeed.
Can't really understand the reason why they used that sharing address method... and with WatchDog register... well... yes and no... but certainely not 100%.
Question is... do they have an answer for that themself?
Universal answer??? Because!
