Function
Power supply for the internal LSI.
Connect all Vcc pins to the system.
There will be no operation if any pins
are open.
Ground pin. Connect all Vss pins to
the system power supply (0V). There
will be no operation if any pins are
open.
Power supply for I/O pins. Connect
all VccQ pins to the system power
supply. There will be no operation if
any pins are open.
Ground pin. Connect all VssQ pins to
the system power supply (0V). There
will be no operation if any pins are
open.
Power supply for the on-chip PLL1
oscillator
Ground pin for the on-chip PLL1
oscillator
Power supply for the on-chip PLL2
oscillator
Ground pin for the on-chip PLL2
oscillator
Connected to a crystal resonator.
An external clock signal may also be
input to the EXTAL pin. For
examples of the connection of crystal
resonator or an external clock signal,
see section 4, Clock Pulse
Generator (CPG).
