Section 20 Serial IO (SIOF)
(2) Control by Secondary FS
This is the method that CODEC, which outputs SIOFSYNC as a sync. pulse (FS), transmit or
receive the control data by outputting the secondary FS used for transmit or receive for only
control data after the period of 1/2 frame, which is different from the original FS output position.
Order of the control data interface as secondary FS are listed below.
• Normal data are sent as LSB=0 (compulsory is 0 by SIOF)
• Transmit data of LSB=1 at transmitting the control data
• CODEC transmits secondary FS
• SIOF synchronizes secondary FS and transmit or receive (storing into SIRCR register) the
Figure 20.8 shows timing of control data interface by secondary FS.
