Caution

Select the TTL input buffer and the N-ch open drain output (VDD tolerance (for the 20- to 52-pin

products)/EVDD tolerance (for the 64- to 100-pin products)) mode for the SDAr pin and the N-ch open

drain output (VDD tolerance (for the 20- to 52-pin products)/EVDD tolerance (for the 64- to 100-pin

products)) mode for the SCLr pin by using port input mode register g (PIMg) and port output mode
