Trace program enable:

0

The ETM trace unit interface in the processor 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 processor is enabled, and clocks are enabled. Writes to most trace registers are ignored


The TRCPRGCTLR can be accessed through the external debug interface, offset 0x004.
