Reserved
Reserved. Any values read should be ignored. When writing to this field always write
with reset value.
[15]
BRK1PINV
Brake 1 Pin Inverse
0 = The state of pin PWM0_BRAKE1 is passed to the negative edge detector.
1 = The inversed state of pin PWM0_BRAKE1 is passed to the negative edge detector.
[14:12]
BRK1FCNT
Brake 1 Edge Detector Filter Count
The register bits control the Brake1 filter counter to count from 0 to BRK1FCNT.
[11:9]
BRK1NFSEL
Brake 1 Edge Detector Filter Clock Selection
000 = Filter clock = HCLK.
001 = Filter clock = HCLK/2.
010 = Filter clock = HCLK/4.
011 = Filter clock = HCLK/8.
100 = Filter clock = HCLK/16.
101 = Filter clock = HCLK/32.
110 = Filter clock = HCLK/64.
111 = Filter clock = HCLK/128.
[8]
BRK1NFEN
PWM Brake 1 Noise Filter Enable Bit
0 = Noise filter of PWM Brake 1 Disabled.
1 = Noise filter of PWM Brake 1 Enabled.
[7]
BRK0PINV
Brake 0 Pin Inverse
0 = The state of pin PWM0_BRAKE0 is passed to the negative edge detector.
1 = The inversed state of pin PWM0_BRAKE1 is passed to the negative edge detector.
[6:4]
BRK0FCNT
Brake 0 Edge Detector Filter Count
The register bits control the Brake0 filter counter to count from 0 to BRK1FCNT.
