9 Description:
10                 Reading returns either '1' or '0'.
11                 '1' means that the clock in question is present.
12                 '0' means that the clock is missing.

17 Description:
18                 Reading returns either '1' or '0'. '1' means that the
19                 pllY is locked.

24 Description:
25                 Writing '1' triggers the clock distribution synchronization
26                 functionality. All dividers are reset and the channels start
27                 with their predefined phase offsets (out_altvoltageY_phase).
28                 Writing this file has the effect as driving the external
29                 /SYNC pin low.
