R/W 000
Scaling for CLA Input Data
000 = CLA Value (Default)
001 = CLA Value multiplied by 2
010 = CLA Value divided by 2
011 = CLA Value multiplied by 4
100 = CLA Value divided by 4
101 = CLA Value multiplied by 8
110 = CLA Value divided by 8
111 = CLA Value
R/W 0
Slave DPWM to external sync
0 = DPWM not synchronized to external sync (Default)
1 = Slave DPWM to external sync
R/W 0
Sets if CBC responds to Fault CBC when PWM-B is active, only available in Multi
and Reson modes
0 = Response to Fault CBC when PWM-A active (Default)
1 = Response to Fault CBC when PWM-A or PWM-B active
R/W 0
Auto Switching Mode Select
0 = Auto Switching Mode disabled (Default)
1 = Auto Switching Mode enabled
R/W 01
Update End Period Mode
00 = Events updated anytime
01 = Events updated at End of Period (Default)
10 = Events updated at count value equal to Sample Trigger 2 register
11 = Events updated at End of Period and Sample Trigger 2 position
R/W 0
PWM Check Override
0 = DPWM checks mathematical settings within module, correct placement of Event
settings/period settings. Invalid configurations are not allowed.
1 = Overrides checking for invalid configurations and turns off PWM mathematical
checking functions (Default)
R/W 0
0 = Event calculations use DPWM Period register (Default)
1 = Event calculations use Global Period register
R/W 0
Direction for PWM B pin
0 = PWM B configured as output (Default)
1 = PWM B configured as input
R/W 0
Direction for PWM A pin
0 = PWM A configured as output (Default)
1 = PWM A configured as input
R/W 0
Sets value of PWM B output in GPIO mode
0 = PWM B driven low in GPIO mode (Default)
1 = PWM B driven high in GPIO mode
R/W 0
Enables GPIO mode for PWM B output
0 = PWM B in DPWM mode (Default)
1 = PWM B in GPIO mode
R/W 0
Sets value of PWM A output in GPIO mode
0 = PWM A driven low in GPIO mode (Default)
1 = PWM A driven high in GPIO mode
R/W 0
Enables GPIO mode for PWM A output
0 = PWM A in DPWM mode (Default)
1 = PWM A in GPIO mode
