This example shows how to stop OCLAs on the system.

  The following commands stop all running OCLAS, disable and free up
  system memory associated with each OCLA, and unload the OCLA
  execlet from system memory.

  If a STOP/CPU command is executed, the OCLA is automatically
  disabled, and the cache set used by the OCLA is released to
  the EV7 CPU.

  If a CPU is started by the START/CPU command, normal OCLA commands
  must be used to enable and start the OCLA.

  SDA> OCLA STOP
  OCLA PC tracing stopped for 8 CPUs

  SDA> OCLA DISABLE
  OCLA PC tracing disabled for 8 CPUs

  SDA> OCLA UNLOAD
  OCLA$PCTRACE unload status = 00000001
