dictated by the timing requirements necessary to access the Channel Status memory. Access to the
control register file can be carried out at the full 6 MHz rate. The minimum allowable input sample rate
is 32 kHz, so choosing CCLK to be less than or equal to 4.1 MHz should be safe for all possible
conditions.
