Name and Function
Power supply: For connection to the power supply.
All VCC pins should be connected to the system power
supply.
Ground: For connection to ground
(0 V). All VSS pins should be connected to the system
power supply (0 V).
On-chip step-down power supply pin: The VCL pin
need not be connected to the power supply. Connect
this pin to VSS via a 0.1 µF capacitor (placed close to
the pins).
PLL ground: Ground for on-chip PLL oscillator.
PLL capacitance: External capacitance pin for on-chip
PLL oscillator.
Crystal: Connects to a crystal oscillator.
See section 22A, 22B, Clock Pulse Generator, for
typical connection diagrams for a crystal oscillator.
External clock: Connects to a crystal oscillator.
See section 22A, 22B, Clock Pulse Generator, for
typical connection diagrams for a crystal oscillator.
Subclock: Connects to a 32.768 kHz crystal oscillator.
See section 22A, Clock Pulse Generator, for typical
connection diagrams for a crystal oscillator.
Subclock: Connects to a 32.768 kHz crystal oscillator.
See section 22A, Clock Pulse Generator, for typical
connection diagrams for a crystal oscillator.
System clock: Supplies the system clock to an external
device.
HCAN transmit data: Pin for CAN bus transmission.
Input HCAN receive data: Pin for CAN bus reception.
