15.4.3
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 15.4. The
transfer mode can be specified by the TRMD1 and TRMD0 bits in SIMDR.
