X0
A
Pins for connecting the crystal resonator for the main clock. To
use an eternal clock, input the signal to X0 and leave X1 open.

529
MOD0
B
Memory access mode setting input pins.
Connect the pin directly to Vss.
630
MOD1
731
RST
C
Reset I/O pin.
This pin serves as an N-channel open-drain output with pull-up
resistor and a hysteresis input as well. The pin outputs the “L”
signal (optionally) in response to an internal reset request. Also,
it initializes the
internal circuit upon input of the “L” signal.

P00/INT20/AN4
to P03/INT23/AN7
G
General-purpose CMOS I/O ports.
These pins also serve as an input (wake-up input) of external in-
terrupt 2 or as an A/D converter analog input. The input of ex-
ternal interrupt 2 is a hysteresis input.

P04/INT24 to
P07/INT27
D
General-purpose CMOS I/O ports.
These pins also serve as an input (wake-up input) of external in-
terrupt 2. The input of external interrupt 2 is a hysteresis input.

P30/UCK/SCK
D
General-purpose CMOS I/O ports.
This pin also serves as the clock I/O pin for the UART or 8-bit se-
rial I/O. The resource is a hysteresis input.
18
4
P31/UO/SO
E
General-purpose CMOS I/O ports.
This pin also serves as the data output pin for the UART or 8-bit
serial I/O.
17

P32/UI/SI
E
General-purpose CMOS I/O ports.
This pin also serves as the data input pin for the UART or 8-bit
serial I/O.
15
2
P33/EC
D
General-purpose CMOS I/O ports.
This pin also serves as the external clock input pin for the 8/16-
bit capture timer/counter. The resource is a hysteresis input.
14
1
P34/TO/INT10
D
General-purpose CMOS I/O ports.
This pin also serves as the output pin for the 8/16-bit capture tim-
er/counter or as the input pin for external interrupt 1. The re-
source is a hysteresis input.
13, 12
48, 35
P35/INT11,
P36/INT12
D
General-purpose CMOS I/O ports.
These pins also serve as the input pin for external
interrupt 1. The resource is a hysteresis input.
