Section 17 I
17.4.5
In slave receive mode, the master device outputs the transmit clock and transmit data, and the
slave device returns an acknowledge signal. For slave receive mode operation timing, refer to
figures 17.11 and 17.12. The reception procedure and operations in slave receive mode are
described below.
1. Set the ICE bit in ICCR1 to 1. Set the MLS and WAIT bits in ICMR and the CKS3 to CKS0
2. When the slave address matches in the first frame following detection of the start condition,

bits in ICCR1 to 1. (Initial setting) Set the MST and TRS bits in ICCR1 to select slave receive
mode, and wait until the slave address matches.
the slave device outputs the level specified by ACKBT in ICIER to SDA, at the rise of the 9th
clock pulse. At the same time, RDRF in ICSR is set to read ICDRR (dummy read). (Since the
read data show the slave address and R/W, it is not used.)
