Typical data was characterized at 5.0 V, 25 °C or is recommended value.
The input clock source must be divided using RDIV to within the range of 31.25 kHz to 39.0625 kHz.
This parameter is characterized and not tested on each device. Proper PC board layout procedures must be followed to
achieve specifications.
