TD1 —
CAN1 transmitter output.
External Reset input:
A LOW on this pin resets the device, causing I/O ports
and peripherals to take on their default states, and processor execution to
begin at address 0. TTL with hysteresis, 5 V tolerant.
Input to the oscillator circuit and internal clock generator circuits.
Output from the oscillator amplifier.
Ground:
0 V reference.

This is the power supply voltage for internal
circuitry.
