serout2 apparently changing other I/O?

[rabaggett]

@ Henrik Yep, agreed on all counts. I tried the LATA solution, too, and then found that PIC12F1501 doesn't have LATA...

Correct ANSELA fixed the problem and allowed me to keep the diagnostics.

I also had time to look at the effects of not setting the ANSELA bit on the analog input. While there was no measurable difference near the power supply rails, at 1.2V input a correct setting reduced power consumption by about 700uA.

I can't explain why, but adding a delay before the SEROUT2 didn't change the duration of the pulse... but removing the SEROUT2 removed the problem... curious.

What? It have LATA register, it compile and it works.... maybe you need to upgrade, or double check the chip you compile for?


anyway, since the problem is solved...

mister_e, I just downloaded a new data sheet to prove you wrong. but you're right... I will need spend more time on why it didn't work for me, (And why I didn't find it when I searched my data sheet before...) When I get LATA to compile I'll use that method just for the correct-ness of it.

Yep, that was it. The version of PBP in my shop was current, and had no problem. The copy at the customer's site was ordered from DigiKey, must have been on the shelf a while...
