The RTC is a 16-bit modulo counter that is functional in AM, LPM0, LPM3, and LPM3.5. This module can periodically wake up the CPU from LPM0, LPM3, or LPM3.5 based on timing from a low-power clock source such as the XT1 and VLO clocks. RTC also can be sourced from ACLK controlled by RTCCLK in SYSCFG2. In AM, RTC can be driven by SMCLK to generate high-frequency timing events and interrupts. The RTC overflow events trigger:
RTCSS | CLOCK SOURCE | |
---|---|---|
00 | Reserved | |
01 | SMCLK or ACLK is selected(1) | |
10 | XT1CLK | |
11 | VLOCLK |
