TD1:CAN1 transmitter output.
O
External Reset input: A LOW on this pin resets the device, causing I/O ports and
I peripherals to take on their default states, and processor execution to begin at address 0.
TTL with hysteresis, 5V tolerant.
I Input to the oscillator circuit and internal clock generator circuits.
O Output from the oscillator amplifier.
I Ground: 0V reference.
Analog Ground: 0V reference. This should nominally be the same voltage as V
I
should be isolated to minimize noise and error.
PLL Analog Ground: 0V reference. This should nominally be the same voltage as V
I
should be isolated to minimize noise and error.
I 1.8V Core Power Supply: This is the power supply voltage for internal circuitry.
Analog 1.8V Core Power Supply: This is the power supply voltage for internal circuitry.
I This should be nominally the same voltage as V18 but should be isolated to minimize noise
and error.
I 3.3V Pad Power Supply: This is the power supply voltage for the I/O ports.
Analog 3.3V Pad Power Supply: This should be nominally the same voltage as V3 but
I
should be isolated to minimize noise and error.
