32-kHz RC Oscillator (RCOSC_LF) Not Working
A only.
RCOSC_LF (32.768 kHz) may occasionally produce glitches. The most common symptom when using RCOSC_LF as the low-frequency clock source is that the RTC is advanced or delayed by one SCLK_LF period. However, there may be other consequences, such as system lock-up, potentially leading to an erroneous digital state and unpredicted behavior.
The user must use XOSC_LF as the low-frequency clock source (32.768-kHz crystal is required).
