1 = New reload cycle since last RF clearing
0 = No new reload cycle since last RF clearing
CFX1 - Capture Flag X1
This bit is set when the word count of the Capture X1 FIFO (CX1CNT) exceeds the value of the
CFXWM field. This bit is cleared by writing a one to this bit position if CX1DE is clear (non-DMA
mode) or by the DMA done signal if CX1DE is set (DMA mode). Reset clears this bit.
CFX0 - Capture Flag X0
This bit is set when the word count of the Capture X0 FIFO (CX0CNT) exceeds the value of the
CFXWM field. This bit is cleared by writing a one to this bit position if CX0DE is clear (non-DMA
mode) or by the DMA done signal if CX0DE is set (DMA mode). Reset clears this bit.
CMPF - Compare Flags
These bits are set when the submodule counter value matches the value of one of the VALx registers.
Clear these bits by writing a 1 to a bit position.
1 = A compare event has occurred for a particular VALx value.
0 = No compare event has occurred for a particular VALx value.

Figure 25-47. Interrupt Enable Register (INTEN)
REIE - Reload Error Interrupt Enable
This read/write bit enables the reload error flag (REF) to generate CPU interrupt requests. Reset clears
RIE.
1 = REF CPU interrupt requests enabled
0 = REF CPU interrupt requests disabled
RIE - Reload Interrupt Enable
This read/write bit enables the reload flag (RF) to generate CPU interrupt requests. Reset clears RIE.
1 = RF CPU interrupt requests enabled
0 = RF CPU interrupt requests disabled
CX1IE - Capture X 1 Interrupt Enable
This bit allows the CFX1 flag to create an interrupt request to the CPU. Do not set both this bit and
the CX1DE bit.
1 = Interrupt request enabled for CFX1.
0 = Interrupt request disabled for CFX1.
