The following description gives the procedures for and operations of receiving data in one byte
units by fixing SCL low for every data reception using the HNDS bit function.
1. Perform initialization according to the procedure described in section 14.4.2, Initialization.
2. Confirm that the ICDRF flag is 0. If the ICDRF flag is set to 1, read ICDR and then clear the
3. When the start condition output by the master device is detected, the BBSY flag in ICCR is set
4. When the slave address matches the address in the first frame following the start condition
5. The slave devise returns the data set in the ACKB bit as an acknowledgement at the 9th cycle
6. The IRIC flag is set to 1 at the 9th cycle of the clock. At this time, if the IEIC bit is set to 1, an
7. At the rising edge of the 9th cycle of the clock, the receive data is transferred from ICDRS to
8. Confirm that the STOP bit is cleared to 0, and then clear the IRIC flag to 0.
9. When the next frame is the final receive flame, clear the ACKB bit to 1.
10. After ICDR has been read, the ICDRF flag is cleared to 0 and the SCL bus line is released.
11. After the stop condition (when SCL is high, the SDA is changed from low to high) is detected,
12. Confirm that the STOP bit is set to 1, and then clear the IRIC flag to 0.
Set slave receive mode by clearing the MST and TRS bits to 0. Set the HNDS bit to 1 and the
ACKB bit to 0. To confirm the receive completion, clear the IRIC flag in ICCR to 0.
IRIC flag to 0.
to 1. The master device then outputs the 7-bit slave address and transmit/receive direction
(R/W) data in synchronization with the transmit clock pulses.
generation, the slave device operates as the slave devise specified by the master device. When
the 8th bit of data (R/W) is 0, the TRS bit remains 0 and slave receive operation is performed.
When the 8th bit of data (R/W) is 1, the TRS bit is set to 1 and slave transmit operation is
performed.
When addresses do not match, data receive operation is not performed until the next start
condition is detected.
of the receive frame of the clock.
interrupt request is generated for the CPU.
If the AASX bit is also set to 1, the IRTR flag is set to 1.
ICDRR and the ICDRF flag is set to 1. The slave device keeps SCL low from the falling edge
of the 9th cycle of the receive clock until data in ICDR is read.
This enables master device to transfer the next data.
Receive operation can be continued by repeating steps 5 to 10.
the BBSY flag is cleared to 0 and the STOP bit is set to 1. At this time, if the STOPIM bit is
cleared to 0, the IRIC flag is set to 1.
