Trace program enable:
0 The ETM trace unit interface in the core is disabled, and clocks are enabled only when
necessary to process APB accesses, or drain any already generated trace. This is the
reset value.
1 The ETM trace unit interface in the core is enabled, and clocks are enabled. Writes to
most trace registers are ignored.
Bit fields and details not provided in this description are architecturally defined. See the Arm
