Register summary
Configuration register A (addr 0x00)
Table 10.
The STA326 will support sample rates of 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, and 96 kHz.
Therefore the internal clock will be:
The external clock frequency provided to the XTI pin must be a multiple of the input sample
frequency (fs). The correlation between the input clock and the input sample rate is
determined by the status of the MCSx bits and the IR (input rate) register bits. The MCSx
