R-IN32M3 Series Data Sheet
3. Specifications
3.10 Clocked Serial Interface
3.10.1 Features
- Three-wire serial synchronous data transfer
- Selectable master mode or slave mode
- Multiple slave configuration plus RCB (Recessive Configuration for Broadcasting) thanks to two configurable
chip select output signals (selectable chip selec priority)
- Built-in baud rate generator
- Adjustable baud rate; in slave mode it is determined by the input clock
- Maximum transmission speed: (at 100MHz PCLK operation)
 in master mode: PCLK/4
 in slave mode: PCLK/6
- Phase of clock and data selectable
- Data transfer with MSB or LSB first selectable
- Transfer data length selectable from 7 to 16 bits in 1-bit increments
- Extended data length (EDL) function for transferring more than 16 bits of data
- Three selectable transfer modes:
 Transmission mode
 Reception mode
 Transmission/reception mode
- Error detection (data consistency check, parity, timeout, overflow, overrun)
- Full support of job concept
- 128 words I/O buffer memory
- Memory mode selectable (FIFO, dual buffer, Tx-only buffer, direct access)
- Four different interrupt request signals
 communication interrupt
 reception interrupt
 error interrupt
 job completion interrupt
- Loop back mode (LBM) function for self-test
