Chapter 12 Synchronous Serial Port
12.3.3 Transmit/Receive Operation
When “1” is written to the SnMD1 bit and "1" is written to the SnMD0 bit of the serial port mode register (SIOnMOD0),
this LSI is set to the transmit/receive mode.
When the SnEN bit of the serial port control register (SIOnCON) is set to “1”, transmission/reception starts. When
transmission/reception of 8/16-bit data terminates, a synchronous serial port interrupt (SIOnINT) occurs and the SnEN
bit is set to “0”.
The received data is input from the tertiary function pins (P40/SIN0 or P44/SIN0) or the tertiary function pin (P50/SIN1,
P54SIN1) of GPIO, and the transmitted data is output from the tertiary function pins (P42/SOUT0 or P46/SOUT0) or the
tertiary function pin (P52/SOUT1) of GPIO.
When an internal clock is selected in the serial port mode register (SIOnMOD1), the LSI is set to a master mode and
when an external clock (SCKn) is selected, the LSI is set to a slave mode.
The serial port mode register (SIOnMOD0) enables selection of MSB first/LSB first.
The received data input pin (SINn), the transmitted data output pin (SOUTn), and the transfer clock input/output pin
(SCKn) need to be set to the tertiary function for the Port 4 or to the secondary function for the Port 5.
Figure 12-10 shows the transmit/receive operation waveforms of the synchronous serial port (16-bit length, LSB first,
clock types 0, positive logic).
