pins to the power supply.*
GND pin
Connect all GND pins to GND.*
Analog reference voltage pin
Analog GND pin
Main clock oscillation input pin
Connect to a crystal or ceramic oscillator. Or, input an external
clock.
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.
Clock multiplication factor select pin
Clock multiplication factor is selected from source oscillation (PLL

* 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.
