Master Receiver Operation 

In master receiver operation, the RIIC as a master device outputs the SCL (clock) signal, receives data from the slave 
device, and returns acknowledgements. Since the RIIC must start by sending a slave address to the corresponding slave 
device, this part of the procedure is performed in master transmitter mode, but the subsequent steps are in master receiver 
mode. 

Figure 22.10 shows an example of usage of master reception and figures 22.11 and 22.13 show the timing of operations 
in master reception. 

The following describes the procedure and operations for master reception. 

 
1.  Set the IICRST bit in ICCR1 to 1 (internal reset) and then clear the IICRST bit to 0 (canceling reset) with the ICE bit 

in ICCR1 cleared to 0 (disabling the interface). This initializes the internal state and the various flags of ICSR1. After 
that, set registers SARLy, SARUy, ICSER, ICMR1, ICBRH, and ICBRL (y = 0 to 2), and set the other registers as 
necessary (for initial settings of the RIIC, see figure 22.5). When the necessary register settings have been completed, 
set the ICE bit to 1 (to enable transfer). This step is not necessary if initialization of the RIIC has already been 
completed. 

2.  Read the BBSY flag in ICCR2 to check that the bus is open, and then set the ST bit in ICCR2 to 1 (start condition 

issuance request). Upon receiving the request, the RIIC issues a start condition. When the RIIC detects the start 
condition, the BBSY flag and the START flag in ICSR2 are automatically set to 1 and the ST bit is automatically 
cleared to 0. At this time, if the start condition is detected and the levels for the SDA output and the levels on the 
SDAn line have matched while the ST bit is 1, the RIIC recognizes that issuing of the start condition as requested by 
the ST bit has been successfully completed, and the MST and TRS bits in ICCR2 are automatically set to 1, placing 
the RIIC in master transmitter mode. The TDRE flag in ICSR2 is also automatically set to 1 in response to setting of 
the TRS bit to 1. 

3.  Check that the TDRE flag in ICSR2 is 1, and then write the value for transmission (the first byte indicates the slave 

address and value of the R/W# bit) to ICDRT. Once the data for transmission are written to ICDRT, the TDRE flag is 
automatically cleared to 0, the data are transferred from ICDRT to ICDRS, and the TDRE flag is again set to 1. Once 
the byte containing the slave address and R/W# bit has been transmitted, the value of the ICCR2.TRS bit is 
automatically updated to select master transmitter or master receiver mode in accord with the value of the transmitted 
R/W# bit. If the value of the R/W# bit was 1, the TRS bit is cleared to 0 on the rising edge of the ninth cycle of SCLn 
(the clock signal), placing the RIIC in master receiver mode. At this time, the TDRE flag is automatically cleared to 0 
and the ICSR2.RDRF flag is automatically set to 1. 
Since the ICSR2.NACKF flag being 1 at this time indicates that no slave device recognized the address or there was 
an error in communications, write 1 to the ICCR2.SP bit to issue a stop condition. 
For master reception from a device with a 10-bit address, start by using master transmission to issue the 10-bit 
address, and then issue a restart condition. After that, transmitting 1111 0b, the two higher-order bits of the slave 
address, and the R bit places the RIIC in master receiver mode. 

4.  Dummy read ICDRR after confirming that the RDRF flag in ICSR2 is 1; this makes the RIIC start output of the SCL 

(clock) signal and start data reception.
