Section 17 I
17.7
17.7.1
In master mode, when the start/stop conditions are issued (retransmitted) at the specific timing
under the following condition 1 or 2, such conditions may not be output successfully. To avoid
this, issue (retransmit) the start/stop conditions after the fall of the ninth clock is confirmed. Check
the SCLO bit in the I
1. When the rising of SCL falls behind the time specified in section 17.6, Bit Synchronous
2. When the bit synchronous circuit is activated by extending the low period of eighth and ninth
17.7.2
If the WAIT bit is set to 1, and the SCL signal is driven low for two or more transfer clocks by the
slave device at the eighth and ninth clocks, the high period of ninth clock may be shortened. To
avoid this, set the WAIT bit in ICMR to 0.
