Interrupt in RTC PCF8563TS

Other Parts Discussed in Thread: BQ32002

Hello All,

I am working with PCF8563TS RTC in CC1352R controller, in that I want to know how to use those timer frequencies and how much time i can give to generate interrupt.

And one more point is that there is default frequency is 32.768 Hz with that i have calculated the timing by using that formula:

CountdownPeriod = n / SourceClockFrequency.

I got min 0.030517578125 sec &

max 7.8125 sec

So if i want the interrupt timing should be 5 - 10 min then how can do that.

Thanks,

Hello Sandhya,

Seems you are asking how to setup and use the PCF8563, which, unfortunately, is an NXP device. As such, you will have to contact NXP. If you would like to use a TI device for the RTC, please see the BQ32002: http://www.ti.com/product/bq32002 .

Thanks for reply, I want to ask that in RTC(PCF8563), if we are using timer interrupt, then timing of that interrupt generation. and which timer clock frequency we can use to generate imterrupt.

Thanks,
