1. Schmitt Trigger inputs are: FAULTA0, TCS, TCK, TMS, TDI, RESET, and TRST

2. Analog inputs are: ANA[0:7], XTAL and EXTAL. Specification assumes ADC is not sampling.

3. PWM pin output source current measured with 50% duty cycle.

4. PWM pin output sink current measured with 50% duty cycle.

5. IDDT = IDD + IDDA (Total supply current for VDD + VDDA)

6. Run (operating) IDD measured using 8MHz clock source. All inputs 0.2V from rail; outputs unloaded. All ports configured as inputs;

measured with all modules enabled.

7. Wait IDD measured using external square wave clock source (fosc = 8MHz) into XTAL; all inputs 0.2V from rail; no DC loads; less

than 50pF on all outputs. CL = 20pF on EXTAL; all ports configured as inputs; EXTAL capacitance linearly affects wait IDD; measured

with PLL enabled.

8. This low voltage interrupt monitors the VDDA external power supply. VDDA is generally connected to the same potential as VDD via

separate traces. If VDDA drops below VEIO, an interrupt is generated. Functionality of the device is guaranteed under transient conditions

when VDDA>VEIO (between the minimum specified VDD and the point when the VEIO interrupt is generated).

9. This low voltage interrupt monitors the internally regulated core power supply. If the output from the internal voltage is regulator

drops below VEIC, an interrupt is generated. Since the core logic supply is internally regulated, this interrupt will not be generated unless

the external power supply drops below the minimum specified value (3.0V).
