Test Conditions/Comments
When using the pin selected frequency settings, the device
requires a 25 MHz crystal to support holdover functionality
Using a crystal with a specified load capacitance other than 10 pF
(8 pF to 24 pF) is possible, but necessitates using the SPI port to
alter the default register values for load capacitance
