Notes:
1. Analog source impedance affects the ADC offset voltage (because of pin leakage) and input settling time.
2. Devices are factory calibrated at V_DD = 3.3 V and T_A = +30°C, so the ADC is maximally accurate under these
conditions.
3. LSBs are defined assuming 10-bit resolution.
4. This is the maximum recommended resistance seen by the ADC input pin.
5. The input impedance is inversely proportional to the system clock frequency.

General Purpose I/O Port Input Data Sample Timing
Figure 29 displays a timing sequence for the GPIO port input sampling. The input value
on a GPIO port pin is sampled on the rising edge of the system clock. The port value is
