Function
Power supply for the internal
modules and ports for the system.
Connect all Vcc pins to the system
power supply. There will be no
operation if any pins are open.
Ground pin. Connect all Vss pins to
the system power supply (0 V).
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 (0 V).
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.
For connection to a crystal
resonator. An external clock signal
may also be input to the EXTAL
pin.
For connection to a crystal
resonator.
Supplies the system clock to
external devices.
