9*4882a593SmuzhiyunDescription:
10*4882a593Smuzhiyun		Reading returns either '1' or '0'.
11*4882a593Smuzhiyun
12*4882a593Smuzhiyun		'1' means that the clock in question is present.
13*4882a593Smuzhiyun
14*4882a593Smuzhiyun		'0' means that the clock is missing.

19*4882a593SmuzhiyunDescription:
20*4882a593Smuzhiyun		Reading returns either '1' or '0'. '1' means that the
21*4882a593Smuzhiyun		pllY is locked.

26*4882a593SmuzhiyunDescription:
27*4882a593Smuzhiyun		Writing '1' triggers the clock distribution synchronization
28*4882a593Smuzhiyun		functionality. All dividers are reset and the channels start
29*4882a593Smuzhiyun		with their predefined phase offsets (out_altvoltageY_phase).
30*4882a593Smuzhiyun		Writing this file has the effect as driving the external
31*4882a593Smuzhiyun		/SYNC pin low.
