Note 1.

The value must also be equal to or less than fMCK/4.

Note 2.

Use it with VDD

 Vb.

Note 3.

Set the fMCK value to keep the hold time of SCLr = “L” and SCLr = “H”.

Caution

Select the TTL input buffer and the N-ch open drain output (VDD tolerance) mode for the SDAr pin and the N-ch

open drain output (VDD tolerance) mode for the SCLr pin by using port input mode register g (PIMg) and port

output mode register g (POMg). For VIH and VIL, see the DC characteristics with TTL input buffer selected.

(Remarks are listed on the next page.)
