Apply 2.7V to 5.5V to the VCC pin. Apply 0V to
the VSS pin
Analog Power Supply
Input
AVCC
AVSS
I
Power supply input pins to A/D converter.
Connect AVCC to VCC. Apply 0V to AVSS.
Connect a capacitor between AVCC and AVSS.
Reset Input
RESET
I
Input “L” on this pin resets the MCU
MODE
I
Connect this pin to VCC via a resistor
Main Clock Input
XIN
I
These pins are provided for the main clock
generation circuit I/O. Connect a ceramic
resonator or a crystal oscillator between the XIN
and XOUT pins. To use an externally derived
clock, input it to the XIN pin and leave the XOUT
pin open.
Main Clock Output
XOUT

Data I/O pin
Reference Voltage
Input
VREF
I
Reference voltage input pin to A/D converter
Connect VREF to VCC
A/D Converter
AN8 to AN11
I
Analog input pins to A/D converter
I/O Port
P1_0 to P1_7, P3_3
to P3_5, P3_7, P4_5
I/O
These are CMOS I/O ports. Each port contains
an I/O select direction register, allowing each
pin in that port to be directed for input or output
individually.
Any port set to input can select whether to use a
pull-up resistor or not by program.
P1_0 to P1_3 also function as LED drive ports.
Input Port
P4_6, P4_7
I
Port for input-only
