9.3.7 Event Trigger/Emergency Stop Trigger Control
9.3.7.1 Trigger Signal
The functional timer can accept two types of trigger signal: event trigger and emergency stop trigger.
The event trigger is used as counter start/stop or trigger for capture.
The trigger source can be chosen from EXTRG0 to EXTRG7, CMP0D, TMH0TRG to TMH5TRG, or FTMnTRG.
The emergency stop trigger used to stop the timer operation, stops the counter and makes the Positive/Negative output
"L" level.
The trigger source can be chosen from EXTRG0, EXTRG4, and CMP0D.
The output of sampling controller is connected to EXTRG0 to EXTRG7. Sampling can be chosen using the port
controller register. In addition, the sampling controller is installed also in the functional timer. It can be set through
FTnTRF2 to FTnTRF0 bits of the FTnTRG1 register.
If EXTRG0 to EXTRG7 and CMP0D are chosen as the emergency stop trigger, sampling is not available on the
functional timer.
Use the external interrupt function and the sampling controller of the analogue comparator.
The interrupt sources of 16-bit timer and functional timer can be set through registers of each timer.
