the TCBLD pin.
10.2 Serial Audio Port
The serial audio input port data format is selected as shown in Table 3, and may be set to master
or slave by the state of the APMS input pin. The OMCK clock ratio is selected as shown in
Table 4. Table 5 describes the equivalent software mode, bit settings for each of the available for-
mats. Timing diagrams are shown in Figure 7.
