NAME I/O
41 AVCC - A/D converter analog power pin
42 AVRH - A/D converter analog reference voltage input
pin.
43 AVSS - A/D converter GND pin
44 SDA2_2 O Multi-function serial interface ch.2 output pin.
This pin operates as SOT2 when it is used in
a UART/CSIO (operation modes 0 to 2) and
as SDA2 when it is used in an I2C (operation
mode 4).
45 SCL2_2 I/O Multi-function serial interface ch.2 clock I/
O pin. This pin operates as SCK2 when it is
used in a UART/CSIO (operation modes 0
to 2) and as SCL2 when it is used in an I2C
(operation mode 4).
46 P23 I/O General-purpose I/O port 2
47 P22/SDA0_0 I/O General-purpose I/O port 2/Multi-function
serial interface ch.0 output pin. This pin
operates as SOT0 when it is used in a UART/
CSIO (operation modes 0 to 2) and as SDA0
when it is used in an I2C (operation mode 4).
48 SIN0_0 I Multi-function serial interface ch.0 input pin.
49 P00/TRSTX I/O General-purpose I/O port 0/J-TAG reset Input
pin.
50 P01/TCK I/O General-purpose I/O port 0/J-TAG test clock
input pin.
