Conditions and notes
Open drain output
P7, PA and PB are output only pins.
P2, P3, P6 and P9 are Schmitt inputs.
Built-in pull-up
resistor output
P7, PA and PB are output only pins.
P2, P3, P6 and P9 are Schmitt inputs.
CMOS outputs (P2, P3, P6, P9 and PC) and pull-up MOS outputs
(P0, P1, P4, P5, P7, PA and PB) are differentiated.
• The P8 circuits can be selected from the following two options in bit units.
