Features
Description
Rev: 2.3.0.1
The Real Time Counter (RTC) enables periodic interrupts at long intervals, or accurate mea-
surement of real-time sequences. The RTC is fed from a 16-bit prescaler, which is clocked from
the RC oscillator or the 32 KHz oscillator. Any tapping of the prescaler can be selected as clock
source for the RTC, enabling both high resolution and long timeouts. The prescaler cannot be
written directly, but can be cleared by the user.
The RTC can generate an interrupt when the counter wraps around the value stored in the top
register, producing accurate periodic interrupts.
32-bit real-time counter with 16-bit prescaler
Clocked from RC oscillator or 32 KHz oscillator
High resolution: Max count frequency 16 KHz
Long delays
Extremely low power consumption
Available in all sleep modes except Static
Interrupt on wrap
– Max timeout 272 years
