38.2 Register Descriptions
38.2.1 RSPI Control Register (SPCR)
Do not change the SPCR.MSTR, SPCR.MODFEN, or SPCR.TXMD bit while the SPCR.SPE bit is 1.
SPMS Bit (RSPI Mode Select)
The SPMS bit selects SPI operation (4-wire method) or clock synchronous operation (3-wire method).
The SSLA0, SSLA1, and SSLA3 pins are not used in clock synchronous operation. The RSPCKA, MOSIA, and MISOA
pins handle communications. If clock synchronous operation is to proceed in master mode (SPCR.MSTR = 1), the
SPCMDm.CPHA bit can be set to either 0 or 1. Set the CPHA bit to 1 if clock synchronous operation is to proceed in
slave mode (SPCR.MSTR = 0). Do not set the CPHA bit to 0 when clock synchronous operation is to proceed in slave
mode (SPCR.MSTR = 0).
TXMD Bit (Communications Operating Mode Select)
The TXMD bit selects full-duplex synchronous serial communications or transmit operations only.
When performing communications with the TXMD bit set to 1, the RSPI performs only transmit operations and not
receive operations (refer to
section 38.3.6, Communications Operating Mode).
When the TXMD bit is set to 1, receive buffer full interrupt requests cannot be used.
