Real Time Clock
The RTC (Real Time Clock) provides an automatic wake-up to manage all low-power modes.
Overview
The RTC (Real Time Clock) provides an automatic wake-up to manage all low-power modes. It is an independent timer. The RTC provides a set of continuously running counters which can be used, with suitable software, to provide a clockcalendar function. The counter values can be written to set the current time/date of the system. The RTC includes also a periodic programmable wake-up flag with interrupt capability.
Key features
- Programmable pre-scaler: division factor up to 2^20
- 64-bit programmable counter for long-term measurement
- Two separate clocks:
- ICB clock for ICB interface
- RTC clock for RTC Core
- Two separate reset types:
- The ICB interface is reset by icb_rstn
- The RTC Core (Pre-scaler, Alarm, Counter and Divider) is reset by rtc_rstn
- Three dedicated maskable interrupt lines:
- Alarm interrupt, for generating a software programmable alarm interrupt
- Seconds interrupt, for generating a periodic interrupt signal with a programmable period length
- Overflow interrupt, to detect when the internal programmable counter rolls over to zero
- Digital calibration circuit (periodic counter correction) obtained in a calibration window of several seconds
