Read as 0x0. Write has no effect.
Sets Warm-Up Time for the LCOSC.
Sets the "warm up" interval for the LC oscillator, where it is biased up prior to 
transmission or on the transition from OOK zero bit to OOK one bit. Set this value in a
way that the warm-up interval of the LCOSC should be 125 µs for a given ODS clock
rate.
Interval is in 64 x clk_ods cycles resolution
Interval = 64 x ods_warm_lc x (ods_ck_div+1)/24 MHz
Using the Si4010 calculator spreadsheet in order to determine the correct value of
this parameter is strongly recommended.
