DCLK CONTROL REGISTERS (DCLKCON)
This register defines DCLKn signals, which work as clocks for external sources. See the following figure for how to
make the DCLKn signals. The DCLKCON can actually operate only when CLKOUT[1:0] is set to send the DCLKn
signals.

DCLK1 Compare value clock toggle value. (< DCLK1DIV)
If the DCLK1CMP is n, Low level duration is (n + 1).
High level duration is ( (DCLK1DIV + 1) – (n +1) ).
DCLK1 Divide value
DCLK1 frequency = source clock / (DCLK1DIV + 1)

DCLK0 Compare value clock toggle value. (< DCLK0DIV)
If the DCLK0CMP is n, Low level duration is (n + 1).
