Transmit/Receive Timing: The SIOF_TXD transmit timing and SIOF_RXD receive timing
relative to the SIOF_SCK can be set as the sampling timing in the following two ways. The
transmit/receive timing is set using the REDG bit in SIMDR.
•
Falling-edge sampling
•
Rising-edge sampling
Figure 22.4 shows the transmit/receive timing.

22.4.3 Transfer
Data
Format
The SIOF performs the following transfer.
•
Transmit/receive data: Transfer of 8-bit data/16-bit data/16-bit stereo data
•
Control data: Transfer of 16-bit data (uses the specific register as interface)
Transfer Mode: The SIOF supports the following four transfer modes as listed in table 22.6. The
transfer mode can be specified by the bits TRMD[1:0] in SIMDR.

care).
