32-kHz CLOCK OUTPUT
For the RV5C387A, 32.768-kHz clock pulses are output from the 32KOUT pin when either the /CLEN1 bit in
the Control Register 2 or the /CLEN2 bit in the Control Register 1 is set to 0. When both the /CLEN1 and
/CLEN2 bits are set to 0, the 32KOUT pin output is driven high (off). For the RV5C387A, 32.768-kHz clock
pulses are output from the 32KOUT pin regardless of such internal register settings.
