XTO can be calculated out of IMXTO
with CM = 4.37 fF

Crystal oscillator start-up time
Time between ENABLE of the IC with
FSK = H and activation of the CLK
output. The CLK is activated
synchronously to the output frequency
if the current through the XTAL has
reached 35% to 80% of its maximum
amplitude. Crystal parameters:
