operation to stop the TGS counter is not enabled during the first counting cycle, in order to
allow the counting, if the value of the TGSCRR is the same as the value of the TGSCCR.
Figure 306. TGS counter cases
24.4 Scheduler subunit (SU)
The structure of the SU is shown in Figure 307.
The SU generates the trigger event output according to the occurred trigger event, and it
has the same functionality in both TGS modes (triggered mode and sequential mode). Each
of the four SU outputs:
● ADC command or ADC stream of commands
● eTimer1 pulse (ETIMER0_TRG internally connected to eTimer_0 AUX0)
● eTimer2 pulse (ETIMER1_TRG internally connected to eTimer_0 AUX1)
● External trigger pulse
can be linked to any of eight trigger events by the Trigger Handler block. Each trigger event
can be linked to one or more SU outputs.
