RTCCEMLIB

Detailed Description

Real Time Counter (RTCC) Peripheral API.

This module contains functions to control the RTCC peripheral of Silicon Labs 32-bit MCUs and SoCs. The RTCC ensures timekeeping in low energy modes. The RTCC also includes a BCD calendar mode for easy time and date keeping.
