Unless otherwise specified: Vss=0V, V_DD=3V, Topt=−40°C to +85°C, Oscillation frequency=32.768 kHz

(load capacitance C_L=6pF, equivalent series resistance R₁=20kΩ)

(Note 1) In this mode, 32KOUT is disabled and no clock is output from this pin.

For time keeping current when outputting 32-kHz pulse from 32KOUT pin (this pin without loading), please refer to “P.7 Typical Performance Curves”.
