The RTC is continuously clocked, and remains operating in all sleep modes except Static. Inter-
rupts are not available in DeepStop mode.
The RTC interrupt line is connected to one of the internal sources of the interrupt controller.
Using the RTC interrupt requires the interrupt controller to be programmed first.
The RTC prescaler is frozen during debug operation, unless the OCD system keeps peripherals
running in debug operation.
The RTC can use the internal RC oscillator as clock source. This oscillator is always enabled
whenever these modules are active. Please refer to the Electrical Characteristics chapter for the
characteristic frequency of this oscillator (f
The RTC can also use the 32 KHz crystal oscillator as clock source. This oscillator must be
enabled before use. Please refer to the Power Manager chapter for details.
The RTC is enabled by writing the EN bit in the CTRL register to 1. The 16-bit prescaler will then
increment on the selected clock. The prescaler cannot be read or written, but it can be reset by
writing the PCLR strobe.
