Operation of Audio Input/Output Port
By setting the audio input ports (DI0 to DI3, LRCKI0 to LRCKI3, and BCKI0 to BCKI3) and the audio output port
(DO0 to DO3, LRCKO, and BCKO) according to the internal register provided in the table 5-10, the formats can
be changed. Figure 12 shows the formats supported by the ML87V5002.
