DCLK1CMP
[27:24]
DCLK1 compare value clock toggle value. ( < DCLK1DIV)
If the DCLK1CMP is n, Low level duration is( n + 1),
High level duration is((DC 1) –( n +1))
DCLK1DIV
[23:20]
DCLK1 divide value
DCLK1 frequency = source clock /( DC 1)
DCLK1SelCK
[17]
Select DCLK1 source clock
0 = PCLK
1 = EPLL
DCLK1EN [16]

enable
0 = DCLK1 disable
1 = DCLK1 enable
DCLK0CMP
[11:8]
DCLK0 compare value clock toggle value.( < DCLK0DIV)
If the DCLK0CMP is n, Low level duration is( n + 1),
High level duration is((DC 1) –( n +1))
DCLK0DIV
[7:4]
DCLK0 divide value.
DCLK0 frequency = source clock /( DC 1)
