This ribbon cable is not only for debugging but also for industrial programming and testing for us and the customers. The connector is from Wurth and
it is quite similar to the TAG CONNECT in its us ...

I think I found something:

I have 2 ways to power supply my board:
- 1 by the normal way: 2 faston +12V/GND (come from laboratory PSU)
- 2 by my debugging board which include FT232 / 12VDC PSU fr ...

He didn't mean to try it without PUT. He wondered if you had it at all.

I would try it with PUT_64MS.

Same with PUT_64MS.

Same without PUT...

I don't think I have any problem with my power supply because this PSU is common for a lot of our projects and we have certification for it.

I can't have board layout issue because I use a 4 layers ...

That is interesting. Suggests it is the period spent in the transition
(deciding whether to switch to battery or not), that is causing the issue.
Do you have the brownout enabled?. What voltage it ...

The last one I use is the STM32F746BET6. On the "Power supply scheme" they don't use capacitor on Vbat. On my biggest STM32 dev board, STM3240G-EVAL, they don't use capacitor on Vbat.

Do ...

Thanks for your time PCM programmer and Ttelmah but I will not use the internal RTCC because of the poor reliability.

I never use an internal RTCC with a PIC but regularity with STM32.
On STM32 I used ST never put a capacitor on Vbat pin.

I don't find this information on the PIC16F19176 datasheet but I tried with ...

Seriously there should not be any detectable ripple on the Vbat connection. 2 or 3mV at most.
-> yes I have ripple on Vbat juste enough for stop my scope with a 2.9V trig level, this is the MCU r ...

In some case even if I don't run the setup_rtc function my RTCC restart at 00:00:00 in case of a 0x0B3C restart cause...

I migrate from a PIC16F1936 + DS1307 to this PIC16F19176 with internal RTCC, ...

I add this setup code:

I lost my time, during a switch off, only if my restart cause is:
0x0B3C
0x0B34

And never with this restart causes:

PCM programmer:
I try you little code. Now my RTCC start working after a 'Y' with my custom date and time or 'N' with default date and time.

The only difference with my code was my reaction time. ...

shouldn't set_clock(write_clock); be set_clock(&write_clock); instead?

Nope...
