| Description | Controls TMC operating mode. When configured as an ETB or ETR, the TMC can operate in the following modes:<ul><li>Software FIFO mode</li><li>Circular Buffer mode.</li></ul> When configured as an ETF, the TMC has an additional mode of operation, Hardware FIFO mode. The operating mode can be changed only when the TMC is disabled. Attempting to write to this register while not in Disabled state (TraceCaptEn=0 and TMCReady=1) results in Unpredictable behavior. The operating mode is ignored when in Disabled state. |
