Description
V
DD
I
Power supply pin
Connect all V
DD pins to the power supply.*
GND
I
GND pin
Connect all GND pins to GND.*
V
REF
I
Analog reference voltage pin (Connect to the V
DD pin when A/D
converter is not used.)
Power
supply
AGND
I
Analog GND pin (Connect to the GND pin when A/D converter is not
used.)
OSC0
I
Main clock oscillation input pin
Connect to a crystal or ceramic oscillator. Or, input an external clock.
OSC1
O
Main clock oscillation output pin
Connect to a crystal or ceramic oscillator.
The clock output is opposite in phase to OSC0.
Leave this pin unconnected when an external clock is used.
CLKSEL0
I
Oscillation
CLKSEL1
I
Clock multiplication factor select pin
Clock multiplication factor is selected from source oscillation (PLL
OFF), source oscillation
× 2, or source oscillation × 4
Reset
RES
I
Reset input pin
NMI
I
Non-maskable interrupt input pin
Others
EA
I
External program memory access input pin
If the
EA pin is enabled (low level), the internal program memory is
masked and the CPU executes the program code in external program
memory all address space.
*
Each of the family devices has unique pattern routes for the internal power and ground. Connect the
power supply voltage to all V
DD pins and the ground potential to all GND pins. If a device may have
one or more V
DD or GND pins to which the power supply voltage or the ground potential is not
connected, it can not be guaranteed for normal operation.
