5 V tolerant pad providing digital I/O functions with TTL levels and hysteresis and 10 ns slew rate control.
5 V tolerant pad providing digital I/O functions with TTL levels and hysteresis and 10 ns slew rate control. If configured for an input
function, this pad utilizes built-in glitch filter that blocks pulses shorter than 3 ns.
Open-drain 5 V tolerant digital I/O I
functionality. Open-drain configuration applies to ALL functions on that pin.
5 V tolerant pad providing digital I/O (with TTL levels and hysteresis and 10 ns slew rate control) and analog input function. If configured
for an input function, this pad utilizes built-in glitch filter that blocks pulses shorter than 3 ns. When configured as an ADC input, digital
section of the pad is disabled.
Pad provides special analog functionality.

Description
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.
Ground: 0 V reference.
Analog ground: 0 V reference. This should be nominally the
same voltage as V
and error.
Analog 3.3 V power supply: This should be nominally the
same voltage as V
noise and error. This voltage is used to power the on-chip
PLL. This pin also provides a voltage reference level for the
ADC.
1.8 V core power supply: This is the power supply voltage for
internal circuitry.
3.3 V pad power supply: This is the power supply voltage for
the I/O ports.
RTC power supply: 3.3 V on this pin supplies the power to
the RTC.
