5C338A, setting the CLEN2 bit or the CLEN1 bit (D3 in the control register 2) to 0, and the CLKC pin to
high 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 or CLKC pin to low specifies
disabling (“L”) such output.
