RTC in low power modes

[Mr Alireza Najafi]

Hi

I had a question about RTC in SPC560bxx.

When you read the RTC documentation carefully, you will notice that it is actually a 32-bit counter that also operates in low-power modes and issues interrupts.

This module is just a counter and there is no register to preserve value in low power mode.

Am I right about that?

How to use RTC in low power modes?

Is it used only to wake up the chip?

Thanks

Hello Alireza,

You can find a nice example in SPC5Studio Tools suite

SPC560Dxx_RLA WKPU API Test Application for Discovery

RTC Timer is set to 2 seconds in this example
