22. Serial I/O with FIFO (SIOF)
(2)
The CODEC normally outputs the SIOF_SYNC signal as synchronization pulse (FS). In this
method, the CODEC outputs the secondary FS specific to the control data transfer after 1/2 frame
time has been passed (not the normal FS output timing) to transmit or receive control data. This
method is valid for SIOF slave mode. The following summarizes the control data interface
procedure by the secondary FS.
• Transmit normal transmit data of LSB = 0 (the SIOF forcibly clears to 0).
• To execute control data transmission, send transmit data of LSB = 1 (the SIOF forcibly set to 1
• The CODEC outputs the secondary FS.
• The SIOF transmits or receives (stores in SIRCDR) control data (data specified by SITCDR)
Figure 22.8 shows an example of the control data interface timing by the secondary FS.
