Notes 1. The value must also be f
CLK/4 or lower.
2. 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 (V
DD tolerance (When 25- to 48-pin
products)/EVDD tolerance (When 64-pin products)) mode for the SDAr pin and the N-ch open drain
output (V
DD tolerance (When 25- to 48-pin products)/EVDD tolerance (When 64-pin products)) mode for
the SCLr pin by using port input mode register g (PIMg) and port output mode register g (POMg). For
V
IH and VIL, see the DC characteristics with TTL input buffer selected.
(Remarks are listed on the next page.)
