Last Updated:11/27/2017


Where can I find the references to module guide resources for the RTC HAL module on r_rtc?


Information on the module guide itself and the associated resources and known issues are available here.


The Real-Time Clock (RTC) HAL module is a high-level API for RTC applications and is implemented on r_rtc. The RTC HAL module configures the RTC module and controls clock, calendar, and alarm functions. The RTC uses the real-time clock module on the Synergy MCU. A user-defined callback can be created to respond to any of the three supported interrupt types- alarm, periodic, or carry.

The RTC HAL module supports the following features:

  • RTC peripheral configuration
  • Clock and calendar functions:
  • Alarm, periodic, and carry interrupts
  • Time-capture function
  • Event linkage to other peripherals
