FTnINTS is a special function register (SFR) used to indicate the interrupt status of FTMn.
FTnINTS is a read-only register. Writing to it has no effect.
Description of Bits
•
FTnISP (bit 0)
Indicates the period interrupt state of FTMn.
FTnMD FTnISP Description
TIMER
CAPTURE
PWM1/2
0 Period interrupt has not occurred (initial value)
1
Period interrupt has occurred
This bit is cleared when writing 1 to FTnICP
•
FTnISA (bit 1)
Indicates the state of event timing A interrupt of FTMn.
Indicates that the captured data is stored to FTnEA in the CAPTURE mode.
FTnMD FTnISA Description
TIMER
PWM1/2
0 Event timing A interrupt has not occurred (initial value)
1
Event timing A interrupt has occurred
This bit is cleared when writing 1 to FTnICA
CAPTURE 0 Capture A interrupt has not occurred
1
Capture A interrupt has occurred
This bit is cleared when writing 1 to FTnICA or reading FTnEA
