To switch on Quick Format Change Mode do the following:
1. Set UpdTiming to 2.
2. Set UpdActive to 1.
3. Be aware that all parameter values have to be set within 10 seconds.
Automatic reset of the UpdActive flag
With Quick Format Change Mode you normally have to clear the UpdActive
flag after all desired parameters have been set. Every time the
PARAMUPD_TIMING register is written to with the UpdActive flag set to 1
a 10 second time-out is started / restarted. If the time-out passes before you
clear the UpdActive flag, the UpdActive flag is cleared automatically and all
parameter changes since setting the UpdActive flag to 1 become active auto-
matically.
