Remark
Condition for clearing (CLD0 = 0)
• When the SCLA0 pin is at low level
• When IICE0 = 0 (operation stop)
• Reset
Condition for clearing (DAD0 = 0)
• When the SDAA0 pin is at low level
• When IICE0 = 0 (operation stop)
• Reset
Digital filter can be used only in fast mode.
In fast mode, the transfer clock does not vary, regardless of the DFC0 bit being set (1) or cleared (0).
The digital filter is used for noise elimination in fast mode.
