CFLR3 Latched Indicator Bit
When PWM group input channel 3 has a falling transition, CFLR3 was latched with
the value of PWM down-counter and this bit is set by hardware.
Write 1 to clear this bit to zero.
CRLR3 Latched Indicator Bit
When PWM group input channel 3 has a rising transition, CRLR3 was latched with
the value of PWM down-counter and this bit is set by hardware.
Write 1 to clear this bit to zero.
Reserved
Capture3 Interrupt Indication Flag
If PWM group channel 3 rising latch interrupt is enabled (CRL_IE3=1), a rising
transition occurs at PWM group channel 3 will result in CAPIF3 to high; Similarly, a
falling transition will cause CAPIF3 to be set high if PWM group channel 3 falling
latch interrupt is enabled (CFL_IE3=1).
Write 1 to clear this bit to zero.
