when the stop condition is detected. Transfer is started when communication data is written to IIC0
after the interrupt request is generated. Unless the interrupt is generated when the stop condition is
detected, the device stops in the wait state because the interrupt request is not generated when
communication is started. However, it is not necessary to set SPIE0 to 1 when MSTS0 (bit 7 of IICS0) is
detected by software.
