17.7.1
The bit field ICCR1.CKS[3:0] should not be H'7 or H'F at the same time as NF2CYC.PRS = 1.
17.7.2
In multi-master operation, when the setting for IIC transfer rate (ICCR1.CKS[3:0]) makes this LSI
slower than the other masters, pulse cycles with an unexpected length will infrequently be output
on SCL.
Be sure to specify a transfer rate that is at least 1/1.8 of the fastest transfer rate among the other
masters.
17.7.3
Reading ICDRR around the falling edge of the 8th clock might fail to fetch the receive data.
In addition, when RCVD is set to 1 around the falling edge of the 8th clock and the receive buffer
is full, a stop condition may not be issued.
Use either 1 or 2 below as a measure against the situations above.
1. In master receive mode, read ICDRR before the rising edge of the 8th clock.
2. In master receive mode, set the RCVD bit to 1 so that transfer proceeds in byte units.
