12 | BLANKEN | R/W | 0h | EPWMBLANK enable. This bit enables the EPWMBLANK signal. 0 EPWMBLANK signal is disabled. 1 EPWMBLANK signal is enabled. |
11:8 | BLANKSOURCE | R/W | 0h | EPWMBLANK source select. This bit field determines which EPWMnBLANK is passed on as the EPWMBLANK signal. Where n represents the maximum number of EPWMBLANK signals available on the device: 0 EPWM1BLANK 1 EPWM2BLANK 2 EPWM3BLANK ... n-1 EPWMnBLANK |
7 | SWLOADSEL | R/W | 0h | Software load select. Determines whether DACxVALA is updated from DACxVALS on SYSCLK or EPWMSYNCPER. 0 DACxVALA is updated from DACxVALS on SYSCLK 1 DACxVALA is updated from DACxVALS on EPWMSYNCPER |
6 | RAMPLOADSEL | R/W | 0h | Ramp load select. Determines whether RAMPSTS is updated from RAMPMAXREFA or RAMPMAXREFS when COMPSTS[COMPHSTS] is triggered. 0 RAMPSTS is loaded from RAMPMAXREFA 1 RAMPSTS is loaded from RAMPMAXREFS |
5 | SELREF | R/W | 0h | CMPSS reference select 0 vref_1p8v as reference voltage [default] 1 vdd_1p8v as reference voltage |
4:1 | RAMPSOURCE | R/W | 0h | EPWMSYNCPER source select. Determines which EPWMnSYNCPER signal is used within the CMPSS module. Where n represents the maximum number of EPWMSYNCPER signals available on the device: 0 EPWM1SYNCPER 1 EPWM2SYNCPER 2 EPWM3SYNCPER ... n-1 EPWMnSYNCPER |
0 | DACSOURCE | R/W | 0h | DAC source select. Determines whether DACHVALA is updated from DACHVALS or from the ramp generator. 0 DACHVALA is updated from DACHVALS 1 DACHVALA is updated from the ramp generator |
