[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 3.3 V power supply: This should be nominally the

noise and error. This voltage is used to power the on-chip

PLL. This pin also provides a voltage reference level for the

ADC.
