Circuit

Conditions and notes

Open drain output

P2, P3, P5 and P6 are Schmitt inputs.

Built-in pull-up resistor output

P2, P3, P5 and P6 are Schmitt inputs.

CMOS outputs (P2, P3, P6 and PC) and pull-up MOS

outputs (P0, P1, P4 and P5) are differentiated according to

the drive capacity of the p-channel transistor.

• The PD comparator inputs and the PE three-value inputs are selected in software.
