Figure 3-1 Maximum Run IDD vs. Frequency (see Note 6. in Table 3-4)
3.3 AC Electrical Characteristics
Timing waveforms in Section 3.3 are tested using the VIL and VIHlevels specified in the DC Characteristics
table. In Figure 3-2 the levels of VIH and VIL for an input signal are shown.

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).
10. Power
on reset occurs whenever the internally regulated 2.5V digital supply drops below 1.5V typical. While power is ramping up,
this signal remains active for as long as the internal 2.5V is below 1.5V typical no matter how long the ramp up rate is. The internally
regulated voltage is typically 100 mV less than VDD during ramp up until 2.5V is reached, at which time it self regulates.
