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