11.6 Clock Synchronous Serial Communication with Slave Select Input Function

Channel 0 of SAU0 correspond to the clock synchronous serial communication with slave select input function.
[Data transmission/reception]
 Data length of 7 or 8 bits
 Phase control of transmit/receive data
 MSB/LSB first selectable
 Level setting of transmit/receive data
[Clock control]
 Phase control of I/O clock
 Setting of transfer period by prescaler and internal counter of each channel
 Maximum transfer rate
During slave communication: Max. f
[Interrupt function]
 Transfer end interrupt/buffer empty interrupt
[Error detection flag]
 Overrun error
[Expansion function]
