NCOx_clk
Note 1:
The increment registers are double-buffered to allow for value changes to be made without first disabling the NCO module. The full increment value is loaded into the buffer registers on the
second rising edge of the NCOx_clk signal that occurs immediately after a write to NCOxINCL register. The buffers are not user-accessible and are shown here for reference.
