Notes 1. The pin function can be selected by using ADPC0 register, PM2 register, ADS register, OPAMP0E bit, and

PGAIN bit. Refer to Tables 4-10 to 4-12 of 4.2.3 Port 2.

PD78F0586, 78F0587, 78F0588 (products with operational amplifier) only

3. 44-pin and 48-pin products only

4. 48-pin products only

5. During I

C communication, set SCLA0 and SDAA0 to N-ch open drain output (VDD tolerance) mode by using

POM6 register (refer to 4.3 (5) Port output mode register 6 (POM6)).

6. When using an input compliant with the SMBus specifications in I

C communication, select the SMBus input

buffer by using PIM6 register (refer to 4.3 (4) Port input mode register 6 (PIM6)).
