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.
5 V tolerant pad providing digital I/O with TTL levels and hysteresis and analog output function. When configured as the DAC output,
digital section of the pad is disabled.
Open-drain 5 V tolerant digital I/O pad, compatible with I
functionality. When power is switched off, this pin connected to the I
configuration applies to all functions on this pin.
Pad provides digital I/O and USB functions. It is designed in accordance with the USB specification, revision 2.0 (Full-speed and
Low-speed mode only).

Description
3.3 V supply voltage: This is the power supply voltage for the I/O ports.
not connected pins: These pins must be left unconnected (floating).
3.3 V DC-to-DC converter supply voltage: This is the power supply for
the on-chip DC-to-DC converter.
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.
ADC reference: This should be nominally the same voltage as V
but should be isolated to minimize noise and error. The level on this pin is
used as a reference for ADC and DAC.
RTC power supply: 3.3 V on this pin supplies the power to the RTC.
