TMS320F280039C: what is priority of ePWM AQ "Do nothing"

Part Number: TMS320F280039C

I configure  xA, output controlled by CMPA,CMPB,CNT

My configuration as follow:

TBCTR Period Counter = 100, CNT = 0  Set xA output high  , CMPA = 50 , Set output Low , CMPB = 50 , Do nothing 

->  what happen while Counter = 50 ? will output  xB  be pull low or Still High?
