clock fluctuates from –4 to +2 I

frequency does not increase because the “L” is extended instead of “H” reduction. These are the
values when the SCL clock synchronization by the synchronous function is not performed. The
CCR value is the decimal notation value of the CCR4 to CCR0 bits.
setting values, use V
Do not set 0 to 2 as the CCR value regardless of the VIIC frequency. Set 100 kHz (max.) in
standard clock mode and 400 kHz (max.) in high-speed clock mode to the SCL frequency by
setting the CCR4 to CCR0 bits.
