CFLR1 Latched Indicator Bit
When PWM group input channel 1 has a falling transition, CFLR1 was latched with
the value of PWM down-counter and this bit is set by hardware.
Clear this bit by writing a one to it.
CRLR1 Latched Indicator Bit
When PWM group input channel 1 has a rising transition, CRLR1 was latched with
the value of PWM down-counter and this bit is set by hardware.
Clear this bit by writing a one to it.

Capture1 Interrupt Indication Flag
If PWM group channel 1 rising latch interrupt is enabled (CRL_IE1=1), a rising
transition occurs at PWM group channel 1 will result in CAPIF1 to high; Similarly, a
falling transition will cause CAPIF1 to be set high if PWM group channel 1 falling
latch interrupt is enabled (CFL_IE1=1). This flag is clear by software with a write 1 to
itself.
