1.0 Functional Description (Continued)

No-Acknowledge from the Master. Note that the No-

Acknowledge is typically used as a signal for the slave

indicating that the Master has read its last byte.

1.9 DIGITAL FILTER

The LM63 incorporates a user-configured digital filter to

suppress erroneous Remote Temperature readings due to

noise. The filter is accessed in the Remote Diode Tempera-

ture Filter and Comparator Mode Register. The filter can be

set according to the following table.

Level 2 is maximum filtering.
