9.3.10 Interrupt Source
This section describes the interrupt source and how to clear it.
When a target interrupt enable (FTnIE*) is set to "1", the interrupt status is enabled, and the interrupt controller
is notified of the source.
Note that the emergency stop interrupt enable does not exist. When the emergency stop is enabled, its interrupt is
also enabled.
If the interrupt status is set to "1" for a source, clear it by an appropriate processing.
When the interrupt vector is used, write "1" to FTnIR at the end of the interrupt processing (when exiting the
interrupt vector).
Name Mode Status How to clear
Period coincident
interrupt ALL FTnISP Write "1" to FTnICP
Event A coincident
interrupt TIMER/PWM1/PWM2 FTnISA Write "1" to FTnICA
Capture A interrupt CAPTURE FTnISA Write "1" to FTnICA or read FTnEA
Event B coincident
interrupt TIMER/PWM1 FTnISB Write "1" to FTnICB
Capture B interrupt CAPTURE FTnISB Write "1" to FTnICB or read FTnEB
Trigger stop
interrupt ALL FTnISTS Write "1" to FTnICTS
Trigger start
interrupt ALL FTnISTR Write "1" to FTnICTR
Emergency stop
interrupt ALL FTnISES Write "1" to FTnICES
The period coincident interrupt/event A coincident interrupt/event B coincident interrupt can be selected as
the interrupt trigger output.
