1 0 = Amplitude is corrected using ALC closed loop
1 = Amplitude is corrected opened loop.
7 Set all bits to 0
Width
1 1 = puts the RF1 channel into standby. Standby
powers down all circuitry associated with ch1,
thus reducing power consumption.

1 1 = instructs the device to lock to external source.
No attempt will be made unless a reference
source is detected.
1 0 = Outputs a 10 MHz signal
1 = Outputs a 100 MHz signal

Width
14 14 bit word to set/adjust the internal 10 MHz
TCXO frequency.
2 Set all bits to 0.
Width
14 14 bit word to set/adjust the ALC DAC value. This
is useful to make output adjustment. The current
ALC DAC value can be read back via register 0x25
