Table 20.3 shows a summary of the oscillator bias settings. The SmaRTClock Bias Doubling feature allows
the self-oscillation frequency to be increased (almost doubled) and allows a higher crystal drive strength in
crystal mode. High crystal drive strength is recommended when the crystal is exposed to poor
environmental conditions such as excessive moisture. SmaRTClock Bias Doubling is enabled by setting
BIASX2 (RTC0XCN.5) to 1.
