12. If Fs is lower than 46.875 kHz, the maximum CCLK frequency should be less than 128 Fs. This is dic-
13. Data must be held for sufficient time to bridge the transition time of CCLK.
14. For f
tated by the timing requirements necessary to access the Channel Status and User Bit buffer memory.
Access to the control register file can be carried out at the full 6 MHz rate. The minimum allowable input
sample rate is 8 kHz, so choosing CCLK to be less than or equal to 1.024 MHz should be safe for all
possible conditions.
