mmdiv/mcksel relationship to clocks needed for I
2
S-bus and IEC 958
Notes
1.
For these combinations the duty factor of the output SCK2 clock is not necessarily 50%. These combinations are
therefore not recommended.
This is illegal but possible.

Table 38
Description of the MMAUD register control bits
Note
1.
If enabled, data is written to the CDDA interface from a FIFO located in the CDDA register space. If either ‘daen’ = 1
or ‘iecen’ = 1 (ieccrtl), the interface will become active.
