16.5 I
Figure 16-12 shows the transfer timing for the “start condition”, “address”, “data”, and “stop condition” output via the
I
The acknowledge (ACK) can be generated by either the master or slave device (normally, it is output by the device
that receives 8-bit data).
level period can be extended and a wait can be inserted.
16.5.1 Start conditions
The start conditions for the SCL0 pin and SDA0 pin are signals that the master device generates to the slave device
when starting a serial transfer. When the device is used as a slave, start conditions can be detected.
been detected (SPD0: Bit 0 = 1 in IIC status register 0 (IICS0)). When a start condition is detected, bit 1 (STD0) of
IICS0 is set (to 1).

The following section describes the I
The master device generates the start condition, slave address, and stop condition.
The serial clock (SCL0) is continuously output by the master device. However, in the slave device, the SCL0’s low
A start condition is met when the SCL0 pin is at high level and the SDA0 pin changes from high level to low level.
A start condition is output when bit 1 (STT0) of IIC control register 0 (IICC0) is set (to 1) after a stop condition has
