Temperature Sense
Note: Temperature Sensor is NOT available in the 56F8122 device.
10.3 AC Electrical Characteristics
Tests are conducted using the input levels specified in Table 10-5. Unless otherwise specified,
propagation delays are measured from the 50% to the 50% point, and rise and fall times are measured
between the 10% and 90% points, as shown in Figure 10-1.
