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.
