49Description:
50		(RW) Set mode the of the syncr counter.
51		mode 0 - COUNT[11:0] value represents the approximate number of bytes moved between two ASYNC packet requests
52		mode 1 - the bits COUNT[11:7] are used as a power of 2. for example, we could insert an async packet every 8K
53		data by writing a value 13 to the COUNT[11:7] field.
