Notes 1.
Remark
Condition for clearing (DAD0 = 0)
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.
When the SDAA0 pin is at low level
When IICE0 = 0 (operation stop)

IICE0: Bit 7 of IICA control register 0 (IICACTL0)
Bits 4 and 5 are read-only.
The status of IICAS0 must be checked and WUP must be set during the period shown
below.
The SDAA0 pin was detected at low level.
The SDAA0 pin was detected at high level.
Operates in standard mode.
Operates in fast mode.
Digital filter off.
Digital filter on.
Check the IICAS0 operation status and set
WUP during this period.
