12.3.2
When “0” is written to the S0MD1 bit and “1” is written to the S0MD0 bit of the serial mode register (SIO0MOD0),
this LSI is set to a receive mode.
When the S0EN bit of the serial port control register (SIO0CON) is set to “1”, reception starts. When reception of
8/16-bit data terminates, a synchronous serial port interrupt (SIO0INT) occurs and the S0EN bit is set to “0”.
Receive data is input from the tertiary function pins (P40/SIN0 or P44/SIN0) of GPIO.
When an internal clock is selected in the serial port mode register (SIO0MD1), the LSI is set to a master mode and
when an external clock (P41/SCK0 or P45/SCK0) is selected, the LSI is set to a slave mode.
The serial port mode register (SIO0MOD0) enables selection of MSB first or LSB first.
The receive data input pin (P40/SIN0 or P44/SIN0) and transfer clock input/output pin (P41/SCK0 or P45/SCK0) must
be set to the tertiary function.
Figures 12-4 and 12-5 show the receive operation waveforms of the synchronous serial ports for clock type 0 and clock
type 1, respectively (8-bit length, MSB first, clock types 0 and 1).
Note:
When the SOUT0 pin is set to the tertiary function output in receive mode, a “H” level is output from the SOUT0
output pin.
