| Date: November 2014 |
| KernelVersion: 3.19 |
| Contact: Mathieu Poirier <mathieu.poirier@linaro.org> |
| Description: (RW) Disables write access to the Trace RAM by stopping the |
| formatter after a defined number of words have been stored |
| following the trigger event. The number of 32-bit words written |
| into the Trace RAM following the trigger event is equal to the |
| value stored in this register+1 (from ARM ETB-TRM). |
