[17]
CRLIEN3
Channel 3 Rising Latch Interrupt Enable
0 = Disable rising edge latch interrupt.
1 = Enable rising edge latch interrupt.
When enabled, capture block generates an interrupt on rising edge of input.
[16]
CAPINV3
Channel 3 Inverter ON/OFF
0 = Inverter OFF.
1 = Inverter ON. Reverse the input signal from GPIO before Capture timer
[15:8]
Reserved
Reserved.

CFLIF2
PWM_FCAPDAT2 Latched Indicator Bit
When input channel 2 has a
falling
transition, PWM_FCAPDAT2 was latched with
the value of PWM down-counter and this bit is set by hardware, software can clear
this bit by writing a zero to it.
[6]
CRLIF2
PWM_RCAPDAT2 Latched Indicator Bit
When input channel 2 has a
rising
transition, PWM_RCAPDAT2 was latched with
the value of PWM down-counter and this bit is set by hardware, software can clear
this bit by writing a zero to it.

Reserved
Reserved.

CAPIF2
Capture2 Interrupt Indication Flag
If channel 2 rising latch interrupt is enabled (CRLIEN2 = 1), a rising transition at input
channel 2 will result in CAPIF2 to high; Similarly, a falling transition will cause
CAPIF2 to be set high if channel 2 falling latch interrupt is enabled (CFLIEN2 = 1).
This flag is cleared by software writing a ‘1’ to it.
[3]
CAPEN2
Capture Channel 2 Transition Enable/Disable
0 = Disable capture function on channel 0.
1 = Enable capture function on channel 0.
When enabled, Capture function latches the PMW-counter to RCAPDAT (Rising
latch) and FCAPDAT (Falling latch) registers on input edge transition.
When disabled, Capture function is inactive as is interrupt.
[2]
CFLIEN2
Channel 2 Falling Latch Interrupt Enable ON/OFF
0 = Disable falling latch interrupt.
1 = Enable falling latch interrupt.
When enabled, capture block generates an interrupt on falling edge of input.
[1]
CRLIEN2
Channel 2 Rising Latch Interrupt Enable ON/OFF
0 = Disable rising latch interrupt.
1 = Enable rising latch interrupt.
When enabled, capture block generates an interrupt on rising edge of input.
[0]
CAPINV2
Channel 2 Inverter ON/OFF
0 = Inverter OFF.
1 = Inverter ON. Reverse the input signal from GPIO before Capture timer
