6.6.4.5 Capture Operation
The Capture 0 and PWM 0 share one timer that included in PWM 0; and the Capture 1 and PWM
1 share another timer, and etc. The capture always latches PWM-counter to CRLRx when input
channel has a rising transition and latches PWM-counter to CFLRx when input channel has a
falling transition. Capture channel 0 interrupt is programmable by setting CCR0[1] (Rising latch
Interrupt enable) and CCR0[2] (Falling latch Interrupt enable) to decide the condition of interrupt
occur. Capture channel 1 has the same feature by setting CCR0[17] and CCR0[18], and etc.
Whenever the Capture module issues a capture interrupt, the corresponding PWM counter will be
reloaded with CNRx at this moment. Note that the corresponding GPIO pins must be configured
as capture function (disable POE and enable CAPENR) for the corresponding capture channel.
