EDGCNTB
Edge Counter B
This read-only field contains the edge counter value for the PWM_B input capture circuitry.
EDGCMPB Edge Compare B
This read/write field is the compare value associated with the edge counter for the PWM_B input capture
circuitry.

PWMA_SMnCAPTCTRLX field descriptions
Field Description
15–13
CX1CNT
Capture X1 FIFO Word Count
This field reflects the number of words in the Capture X1 FIFO. (FIFO depth is 1)
12–10
CX0CNT
Capture X0 FIFO Word Count
This field reflects the number of words in the Capture X0 FIFO. (FIFO depth is 1)
9–8
CFXWM
Capture X FIFOs Water Mark
This field represents the water mark level for capture X FIFOs. The capture flags, STS[CFX1] and
STS[CFX0], won’t be set until the word count of the corresponding FIFO is greater than this water mark
level. (FIFO depth is 1)
7
EDGCNTX_EN
Edge Counter X Enable
This bit enables the edge counter which counts rising and falling edges on the PWM_X input signal.
0 Edge counter disabled and held in reset
1 Edge counter enabled
6
INP_SELX
Input Select X
This bit selects between the raw PWM_X input signal and the output of the edge counter/compare circuitry
as the source for the input capture circuit.
