1
Disabling the 32-kHz clock circuit
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 /CLEN2 bit to 1 disabling (”H”) such output.
(4) TEST
Test Bit

0
Normal operation mode.
1
