5 V tolerant pad providing digital I/O functions with TTL levels and hysteresis.
5 V tolerant pad providing digital I/O functions (with TTL levels and hysteresis) and analog input. When configured as a ADC input,
digital section of the pad is disabled and the pin is not 5 V tolerant.

Rev. 6.01 — 11 March 2011
Description
TDI — Test Data in for JTAG interface.
TMS — Test Mode Select for JTAG interface.
SWDIO — Serial wire debug data input/output.
TRST — Test Reset for JTAG interface.
TCK — Test Clock for JTAG interface.
SWDCLK — Serial wire clock.
RTCK — JTAG interface control signal.
RSTOUT — This is a 3.3 V pin. LOW on this pin indicates the
microcontroller being in Reset state.
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.
Input to the RTC oscillator circuit.
Output from the RTC oscillator circuit.
ground: 0 V reference.
analog ground: 0 V reference. This should nominally be the same
voltage as V
3.3 V supply voltage: This is the power supply voltage for the I/O
ports.
3.3 V voltage regulator supply voltage: This is the supply voltage for
the on-chip voltage regulator only.
analog 3.3 V pad supply voltage: This should be nominally the same
voltage as V
This voltage is used to power the ADC and DAC. This pin should be
tied to 3.3 V if the ADC and DAC are not used.
ADC positive reference voltage: This should be nominally the same
voltage as V
Level on this pin is used as a reference for ADC and DAC. This pin
should be tied to 3.3 V if the ADC and DAC are not used.
ADC negative reference voltage: This should be nominally the same
voltage as V
Level on this pin is used as a reference for ADC and DAC.
RTC pin power supply: 3.3 V on this pin supplies the power to the
RTC peripheral.
