Extended analog input pin for the A/D converter or output pin in
external op-amp connection mode
ANEX1
I
Extended analog input pin for the A/D converter
D/A converter
DA0, DA1

Intelligent I/O
IIO0_0 to IIO0_7
I/O
Input pins for the time measurement function or output pins for
the waveform generating function
IIO1_0 to IIO1_7
I/O

I/O port
P0_0 to P0_7,
P1_0 to P1_7,
P2_0 to P2_7,
P3_0 to P3_7,
P4_0 to P4_7,
P5_0 to P5_7
P6_0 to P6_7,
P7_0 to P7_7,
P9_0 to P9_7,
P10_0 to P10_7
I/O
8-bit CMOS I/O ports. The Port Pi Direction Register determines
whether each pin is used as an input port or an output port. The
Pull-Up Control Register determines if the input ports, divided into
groups of four, are pulled up or not.
P7_0 and P7_1 are N-channel open drain output ports.
P8_0 to P8_4
P8_6, P8_7
I/O
These I/O ports are functionally equivalent to P0.
Input port
P8_5
I
Shares a pin with NMI. Input-only port to read NMI pin level
