Name and Function
Power
VCC
Input
Power supply: For connection to the power supply.
All VCC pins should be connected to the system power
supply.
PVCC1,
PVCC2
Input
Port power supply pin. Connect all pins to the same
power supply.
VSS
Input
Ground: For connection to ground
(0 V). All VSS pins should be connected to the system
power supply (0 V).
Clock
PLLVCC
Input
PLL power supply: Power supply for on-chip PLL
oscillator.
PLLVSS
Input
PLL ground: Ground for on-chip PLL oscillator.
PLLCAP
Input
PLL capacitance: External capacitance pin for on-chip
PLL oscillator.
XTAL
Input
Connects to a crystal oscillator.
See section 23, Clock Pulse Generator, for typical
connection diagrams for a crystal oscillator and
external clock input.
EXTAL
Input
Connects to a crystal oscillator.
The EXTAL pin can also input an external clock.
See section 23, Clock Pulse Generator, for typical
connection diagrams for a crystal oscillator and
external clock input.
OSC1
Input
Subclock: Connects to a 32.768 kHz crystal oscillator.
See Chapter 23 Clock Oscillator for examples of
connections to a crystal oscillator.
OSC2
Input
Subclock: Connects to a 32.768 kHz crystal oscillator.
See Chapter 23 Clock Oscillator for examples of
connections to a crystal oscillator.
ø
Output
System clock: Supplies the system clock to an external
device.
