PRODUCTION DATA.
The RTC counter is a 16-bit modulo counter that is functional in AM, LPM0, LPM3, LPM4, and LPM3.5. This module can periodically wake up the CPU from LPM0, LPM3, LPM4, and LPM3.5 based on timing from a low-power clock source such as the XT1, ACLK, and VLO clocks. In AM, RTC can be driven by SMCLK to generate high-frequency timing events and interrupts. ACLK and SMCLK both can source to the RTC; however, only one of them can be selected at a time. The RTC overflow events can trigger:
