FCRLDENn
Falling Capture Reload Enable Bits
Each bit n controls the corresponding PWM channel n.
0 = Falling capture reload counter Disabled.
1 = Falling capture reload counter Enabled.
[23:22] Reserved Reserved.
[21:16]
RCRLDENn
Rising Capture Reload Enable Bits
Each bit n controls the corresponding PWM channel n.
0 = Rising capture reload counter Disabled.
1 = Rising capture reload counter Enabled.

Reserved.
[13:8] CAPINVn
Capture Inverter Enable Bits
Each bit n controls the corresponding PWM channel n.
0 = Capture source inverter Disabled.
1 = Capture source inverter Enabled. Reverse the input signal from GPIO.

Reserved.
[5:0] CAPENn
Capture Function Enable Bits
Each bit n controls the corresponding PWM channel n.
0 = Capture function Disabled. RCAPDAT/FCAPDAT register will not be updated.
1 = Capture function Enabled. Capture latched the PWM counter value when detected
rising or falling edge of input signal and saved to RCAPDAT (Rising latch) and FCAPDAT
(Falling latch).
