Pin Configuration
P1.29 TCK Test Clock for JTAG interface.
P1.30 TMS Test Mode Select for JTAG interface.
P1.31 TRST Test Reset for JTAG interface.
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,
5V tolerant.
Input to the oscillator circuit and internal clock generator circuits.
Output from the oscillator amplifier.
Ground: 0V reference.
Analog Ground: 0V reference. This should nominally be the same voltage as V
isolated to minimize noise and error.
PLL Analog Ground: 0V reference. This should nominally be the same voltage as V
should be isolated to minimize noise and error.
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. This
should be nominally the same voltage as V18 but should be isolated to minimize noise and error.
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 should
be isolated to minimize noise and error.
