Figure 15-7 shows the operation waveforms of the SDA and SCL signals and the I20BB flag. Table 15-1 shows the
relationship between communication speeds and HSCLK clock counts.
Note
The HSCLK clock count is set so that the communication speed may be set to 100kbps/400kbps when HSCLK is 4
MHz. When the high-speed clock frequency is not 4 MHz, select an I2C0MOD communication speed reduction rate
and an FCON0 HSCLK frequency so that the communication speed may not exceed 100kbps/400kbps.
