Single-chip 16-bit/32-bit microcontrollers
[1]
5 V tolerant pad providing digital I/O functions with TTL levels and hysteresis and 10 ns slew rate control.
[2]
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
2
C-bus 400 kHz specification compatible pad. It requires external pull-up to provide an output
functionality.
[4]
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.

Analog ground:
0 V reference. This should be nominally the
same voltage as V
SS
but should be isolated to minimize noise
and error.
Analog 3.3 V power supply:
This should be nominally the
same voltage as V
DD(3V3)
but should be isolated to minimize
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.
