R2023K/T
32-kHz CLOCK OUTPUT
42
For the R2023K/T, 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 the CLKC pin is set to high. If the
condition is not satisfied, the output is set to low.
