16.4.3
In master receive mode, the master device outputs the receive clock, receives data from the slave
device, and returns an acknowledge signal. The reception procedure and operations in master
receive mode are shown below.
1. Clear the TEND bit in ICSR to 0, then clear the TRS bit in ICCRA to 0 to switch from master
2. When ICDRR is read (dummy data read), reception is started, and the receive clock is output,
3. After the reception of first frame data is completed, the RDRF bit in ICST is set to 1 at the rise
4. The continuous reception is performed by reading ICDRR and clearing RDRF to 0 every time
5. If next frame is the last receive data, set the RCVD bit in ICCR1 to 1 before reading ICDRR.
6. When the RDRF bit is set to 1 at rise of the 9th receive clock pulse, read ICDRR. Then, clear
7. When the STOP bit in ICSR is set to 1, read ICDRR and clear RDRF to 0. Then clear the
8. The operation returns to the slave receive mode.

and data received, in synchronization with the internal clock. The master device outputs the
level specified by ACKBT in ICIER to SDA, at the 9th receive clock pulse.
of 9th receive clock pulse. At this time, the received data is read by reading ICDRR.
RDRF is set. If 8th receive clock pulse falls after reading ICDRR by the other processing while
RDRF is 1, SCL is fixed low until ICDRR is read.
This enables the issuance of the stop condition after the next reception.
