Community Translation: FM3 CSIOの最初の送信データビットが欠落している（KA-03426）
FM3 Clock Synchronous Serial Interface (CSIO) is the general-purpose serial data communication interface (supporting the SPI) to allow synchronous communication with an external device. CSIO is configurable for some transfer operations, for example Normal transfer (I), Normal transfer (II), SPI transfer (I), and SPI transfer (II). CSIO can be configured as Master or Slave.
