TMS320F280049C: ePWM global load

Part Number: TMS320F280049C


(1)GLDCFG register[CMPA_CMPAHR],GLDCFG[TBPRD_TBPRDHR] and so on. If these bits are set, it means TBPRD and TBPRDHR (CMPA and CMPAHR and so on )will all load globally? 

The _ in [CMPA_CMPAHR] means AND?

(2) If I configure the CMPA load on CTR=Zero by 

EPWM_setCounterCompareShadowLoadMode(base2,EPWM_COUNTER_COMPARE_A, EPWM_COMP_LOAD_ON_CNTR_ZERO);

I configure the GLDCFG[CMPA_CMPAHR]=1 as well. Means the register could be loaded when CTR=Zero and global load trigger occur?
