The number of channels in control data is specified by the CD0E and CD1E bits in SICDAR.
Table 21.8 shows the relationship between the number of channels in control data and bit settings.
Table 21.8 Setting Number of Channels in Control Data
Note: To use only one channel in control data, use channel 0.
21.4.5
Control data performs control command output to the CODEC and status input from the CODEC.
The SIOF supports the following two control data interface methods.
• Control by slot position
• Control by secondary FS
Control data is valid only when data length is specified as 16 bits.
(1)
Control data is transferred for all frames transmitted or received by the SIOF by specifying the slot
position of control data. This method can be used in both SIOF master and slave modes. Figure
21.7 shows an example of the control data interface timing by slot position control.
