Chapter 9 Function Timer(FTM)
FEUL620Q504 9–30
The period is calculated as follows:
T
priod
=
FTnP + 1
(FTnP : 0001H to FFFFH)
FTnCK [Hz]
6: Output setting (FTOSL*, Each Port Setting)
Set which output to which port, and reverse.
7: Control start/stop (FTnCON0)
Allow the software start or event trigger reception. Also, set the emergency stop enable.
The counter operates at a falling edge of FTnCK. The software start/stop are synchronized by FTnCK.
FTnSTAT is set to H after FTnCK1 cycle at start, and the counter starts operating after two cycles. At stop,
the counter is stopped in FTnCK1 cycle, and FTnSTAT is set to L. The counter value is kept at this time. If
started again, it restarts after one cycle. To clear the counter, use write access to FTnC.
8: Processing during operation (FTnCON0/1, FTnINTS/C)
The state during operation can be seen in FTnCON1 or FTnINTS. To change the waveform of PWM, etc., set
the period/event and set FTnUD of FTnCON1. Then, it is updated in the next period. Also, setting FTnSDN
of FTnCON0 forces the output to be masked to L.
