Caution Select the TTL input buffer for the SIp pin and the N-ch open drain output (V
DD tolerance (When
20- to 52-pin products)/EV
DD tolerance (When 64- to 128-pin products)) mode for the SOp pin and
SCKp 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.
