Dear Champs,
I am asking this for our customer.
The user has used global load well without HRPWM.
Now, they want to use HRPWM including TBPRDHR, CMPAHR/CMPBHR, DBFEDHR/DEREDHR.
But it seems there is limitation to use HRPWM with global load....
In 20.4.7.2 One-Shot Load Mode, there is a note:
One-shot load mode should NOT be used when high-resolution mode is enabled.
In 20.7.2 Dead-band Submodule Additional Operating Modes, there is a note:
TBPRDHR should not be used with Global load. If high resolution period must be changed in the application, users must write to the individual period registers from an ePWM ISR (The ISR must be synchronous with the PWM switching period), where the Global Load One-Shot bit is also written to.
Questions:
Does that mean global load CANNOT be used with TBPRDHR ONLY, or does that mean global load CANNOT be used with any of HRPWM including TBPRDHR, CMPAHR/CMPBHR, DBFEDHR/DBREDHR
That is, we wonder if below bits of GLDCFG can be used or not?
DBFED_DBFEDHR
DBRED_DBREDHR
CMPB_CMPBHR
CMPA_CMPAHR
TBPRD_TBPRDHR
Would you please confirm them?
Wayne
