Hi Guys,

I am using PIC 18F97j60 , which has a real-time calendar clock pin C3/C4.

I am using 32.768 kHz Xtal EXT:

My version 5.059 ccs. Does anybody has a example? RTC module and functions?

I can't find one in the forum.

Thanks in advance

Your chip does not have an RTCC module. It supports a 32K oscillator on
Timer1, which can be used as a basic RTC. This is on C0/C1, not C3/C4.
Where are you seeing mention of C3/C4 as an real time calendar/clock
in the data sheet for this chip?...

A basic timer1 RTC is posted here:

You would have to tweak the clock setups for your chip.

Sorry. I was remembering the circuit image in my memory[C3/C4].

Now, i took a look at the datasheet [C0/C1].

I'll implement and come back here.

Thanks Ttelmah!
