Chapter 9 Function Timer(FTM)

9.3.7.3 Emergency Stop Operation
When FTnEMGEN is set to "1", the emergency stop function is enabled. Set this bit after the trigger source is
selected in FTnEST.
If an emergency stop trigger input (rising edge) is detected, the counter stops, the output is set to L, and an
emergency stop interrupt occurs.
To restart the counter, clear the emergency stop interrupt status (write "1" to FTnICES) and "1" is set to run bit.
Figure 9-9 shows the operation timing at emergency stop.
After the emergency stop, the RUN bit is cleared to 0, the counter stops after one timer clock, and the STAT bit
is cleared to 0. When the STAT bit is 1, setting the RUN to 1 is not accepted. Confirm that the STAT has
changed to 0 after clearing the interrupt status before running the next RUN.

(1) The counter operation starts at an event trigger (falling edge).
(2) The counter stops at an emergency stop trigger (rising edge). An emergency stop interrupt occurs.
(3) The event trigger is disabled due to the emergency stop in progress.
(4) Clear the emergency stop interrupt to enable the operation.
(5) The counter operation restarts at an event trigger (falling edge).
(In this example, the pulse output restarts after one cycle because the counter is not cleared)
