• Manufacturer Part Number: r8a77850anbg
• Description: Renesas 32-bit Risc Microcomputer Superh? Risc Engine Family
• Manufacturer: Renesas Electronics Corporation.

22.4.3
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 transmit/receive control register as interface)
(1)
As shown in table 22.6, the SIOF supports the following four transfer modes. The transfer mode
can be specified by the TRMD1 and TRMD0 bits in SIMDR.
