CCS/TMS320F28379D: Type #515 a value of type "int" cannot be assigned to an entity of type "union DBFED_REG"

Part Number:TMS320F28379D

Tool/software: Code Composer Studio

I am receiving the following error:

Description Resource Path Location Type
#515 a value of type "int" cannot be assigned to an entity of type "union DBFED_REG" untitled3.c /hbl880 line 174 C/C++ Problem

And the corresponding lines are:

    EPwm1Regs.DBRED = 0;               // Dead-Band Generator Rising Edge Delay Count Register
    EPwm1Regs.DBFED = 0;               // Dead-Band Generator Falling Edge Delay Count Register

How can I fix this? Thank you for your help. 

Note: I am using CCS 6.2
