+ frequency and the scale factor in the SYNC_SCALE register, see
+ Table 154 in the datasheet.
+ The clock-frequency must be:
+ * 1 to 128 Hz for adis1649x devices.

+ The DIOx line to be used as an external clock input.
+ Each DIOx pin supports only one function at a time (data ready line
+ selection or external clock input). When a single pin has two
+ two assignments, the enable bit for the lower priority function
+ automatically resets to zero (disabling the lower priority function).
+ Data ready has highest priority.
+ If not provided then DIO2 is assigned as default external clock
+ input pin.
