Apply voltage of 5 V ± 10 % (typical) to VCC, and 0 V to VSS.
This is connected to VSS.
To enter the reset state, the reset input pin must be kept at a “L” for 2
s or more (under
normal VCC conditions).
If more time is needed for the quartz-crystal oscillator to stabilize, this “L” condition should
be maintained for the required time.
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. If an external clock is used, the clock source should be connected to the XIN pin and
the XOUT pin should be left open.
Port P0 is an 8-bit I/O port with direction register allowing each I/O bit to be individually
programmed as input or output. At reset, this port is set to input mode. The output structure
is N-channel open-drain output. (See note 1)
Pins P00–P05 are also used as PWM output pins PWM0–PWM5 respectively. The output
structure is N-channel open-drain output.
Pins P06 , P07 are also used as external interrupt input pins INT2, INT1 respectively.
P06 pin is also used as analog input pin A-D4.
Port P1 is an 8-bit I/O port and has basically the same functions as port P0. The output
structure is CMOS output. (See note 1)
Pins P10 is also used as OSD output pin OUT2. The output structure is CMOS output.
Pins P11–P14 are used as SCL1, SCL2, SDA1 and SDA2 respectively, when multi-master
I2C-BUS interface is used. The output structure is N-channel open-drain output.
Pins P15–P17 are also used as analog input pins A-D1 to A-D3 respectively.
P15 pin is also used as external interrupt input pin INT3.
Port P2 is an 8-bit I/O port and has basically the same functions as port P0. The output
structure is CMOS output. (See note 1)
Pins P23, P24 are also used as timer external clock input pins TIM3, TIM2 respectively.
P20 pin is also used as serial I/O synchronizing clock input/output pin SCLK. The output
structure is N-channel open-drain output.
Pins P21, P22 are also used as serial I/O data input/output pins SOUT, SIN respectively.
The output structure is N-channel open-drain output.
Ports P30–P32 are a 3-bit I/O port and has basically the same functions as port P0. Either
CMOS output or N-channel open-drain output structure can be selected as the port P30
and P31. The output structure of port P32 is N-channel open-drain output. (See notes 1, 2)
Pins P30, P31 are also used as analog input pins A-D5, A-D6 respectively.
Pins P30, P31 are also used as D-A conversion output pins DA1, DA2 respectively. (See
note 3)
Ports P33, P34 are a 2-bit input port.
P33 pin is also used as OSD clock input pin OSC1.
P34 pin is also used as OSD clock output pin OSC2. The output structure is CMOS output.
