Rev. 1.0
Pin
Name
Input/
Functions
Output
VCC,
Power source
Apply voltage of 5 V ± 10 % to (typical) VCC, and 0 V to VSS.
VSS
CNVSS
This is connected to VSS.
______
RESET
Reset input
Input
To enter the reset state, the reset input pin must be kept at a LOW for 2
s or more (under
normal VCC conditions).
If more time is needed for the quartz-crystal oscillator to stabilize, this LOW condition should
be maintained for the required time.
XIN
Clock input
Input
This chip has an internal clock generating circuit. To control generating frequency, an
external ceramic resonator or a quartz-crystal oscillator is connected between pins XIN and
XOUT
Clock output
Output
XOUT. If an external clock is used, the clock source should be connected to the XIN pin and
the XOUT pin should be left open.
P00/PWM0–
I/O port P0
I/O
Port P0 is an 8-bit I/O port with direction register allowing each I/O bit to be individually
P05/PWM5,
programmed as input or output. At reset, this port is set to input mode. The output structure
P06/INT2/A-D4,
is N-channel open-drain output. (See note 1)
P07/INT1
PWM output
Output
Pins P00–P05 are also used as PWM output pins PWM0–PWM5 respectively. The output
structure is N-channel open-drain output.
External interrupt
Input
Pins P06 and P07 are also used as INT external interrupt input pins INT2 and INT1
input
respectively.
Analog input
Input
P06 pin is also used as analog input pin A-D4.
P10/OUT2/A-D8, I/O port P1
I/O
Port P1 is an 8-bit I/O port and has basically the same functions as port P0. The
P11/SCL1,

P12/SCL2,
OSD output
Output
Pins P10 is also used as OSD output pin OUT2. The output structure is CMOS output.
P13/SDA1,
Multi-master
I/O
Pins P11–P14 are used as SCL1, SCL2, SDA1 and SDA2 respectively, when multi-master
P14/SDA2,
I2C-BUS interface
I2C-BUS interface is used. The output structure is N-channel open-drain output.
P15/INT3/A-D1, Analog input
Input
Pins P10, P15–P17 are also used as analog input pin A-D8, A-D1–A-D3 respectively.
P16/A-D2,
External interrupt
Input
P15 pin is also used as INT external interrupt input pin INT3.
P17/DA2/A-D3
input
DA output
Output
Pins P17 is also used as 14-bit PWM output pin DA2. The output structure is CMOS output.
P20/SCLK,
I/O port P2
I/O
Port P2 is an 8-bit I/O port and has basically the same functions as port P0.
The P21/SOUT(/SIN), output structure is CMOS output. (See note 1)
P22/SIN,
Serial I/O synchronous
I/O
P20 pin is also used as serial I/O synchronous clock input/output pin SCLK. The output
P23/TIM3,
clock input/output port
structure is N-channel open-drain output.
P24/TIM2,
Serial I/O data
I/O
P21 pin is also used as serial I/O data input/output pin SOUT (/SIN). The output
P25–P27
input/output
structure is N-channel open-drain output.
Serial I/O data input
Input
P22 pin is also used as serial I/O data input pin SIN.
External clock
Input
Pins P23 and P24 are also used as timer external clock input pins TIM3 and TIM2
input for timer
respectively.
P30/A-D5,
I/O port P3
I/O
Ports P30–P32 and P35 are a 3-bit I/O port and has basically the same functions as port 0
P31/A-D6,
(see note 1). Either CMOS output or N-channel open-drain output structure can be selected
P32/A-D7,
as ports P30, P31 and P35. The output structure of port P3 2 is N-channel
DA1/P35
open-drain output structure.(See notes 1, 2)
Analog input
Input
Pins P30–P32 are also used as analog input pins A-D5–A-D7 respectively.
DA output
Output
P35 pin is also used as 14-bit PWM output pin DA1. The output structure is CMOS output. At
reset, output is undefined.
