I/O Serial clock (channel 0, 1, 2): Clock I/O pins.
SCK0 output type is NMOS push-pull.
A/D converter AN15 to AN0 Input Analog 15 to 0: Analog input pins.
ADTRG Input A/D conversion external trigger input: Pin for input of
an external trigger to start A/D conversion.
AVCC Input A/D converter power supply pin.
When the A/D converter are not used, this pin should
be connected to the system power supply (+5 V).
AVSS Input Analog circuit ground and reference voltage
A/D converter ground and reference voltage.
Connect to system power supply (0 V).
Vref Input A/D converter reference voltage input pin.
When the A/D converter are not used, this pin should
be connected to the system power supply (+5 V).
I/O ports P17 to P10 I/O Port 1: An 8-bit I/O port. Input or output can be
designated for each bit by means of the port 1 data
direction register (P1DDR).
P37 to P30 I/O Port 3: An 8-bit I/O port. Input or output can be
designated for each bit by means of the port 3 data
direction register (P3DDR).
P47 to P40 Input Port 4: An 8-bit input port.
P77 to P70 I/O Port 7: An 8-bit I/O port. Input or output can be
designated for each bit by means of the port 7 data
direction register (P7DDR).
P97 to P90 Input Port 9: An 8-bit input port.
PA3 to PA0 I/O Port A: A 4-bit I/O port. Input or output can be
designated for each bit by means of the port A data
direction register (PADDR).
PB7 to PB0 I/O Port B: An 8-bit I/O port. Input or output can be
designated for each bit by means of the port B data
direction register (PBDDR).
