13 | Description: (RW) Disables write access to the Trace RAM by stopping the | |
14 | formatter after a defined number of words have been stored | |
15 | following the trigger event. The number of 32-bit words written | |
16 | into the Trace RAM following the trigger event is equal to the | |
17 | value stored in this register+1 (from ARM ETB-TRM). | |
