Description
Enabling the 32-kHz clock circuit
Disabling the 32-kHz clock circuit
(Default setting)
For the RV5C387A, setting the CLEN2 bit or the CLEN1 bit (D3 in the control register 2) to 0, specifies generating
clock pulses with the oscillation frequency of the 32.768-kHz crystal oscillator for output from the 32KOUT pin.
Conversely, setting both the CLEN1 and the CLEN2 bit to 1 specifies disabling (“H”) such output.
