Enables the ITM:
0 Disabled.
1 Enabled.
This is the master enable for the ITM unit. A debugger
must set this bit to 1 to permit writes to all Stimulus
Port registers.
A Power-on reset clears this bit to 0.

Enables Synchronization packet transmission for a
synchronous TPIU:

1 Enabled.
A Power-on reset clears this bit to 0.
Note: If a debugger sets this bit to 1 it must also
configure DWT_CTRL.SYNCTAP for the correct
synchronization speed, see Control register,
DWT_CTRL on Arm TRM page C1-797.
