Why I am getting orange warnings if I try to de-reference a 16 bit pointer variable?

I am trying to access microcontroller registers by using 16 bit pointer variable, but it throws orange polyspace warnings. But when I try to access a 32 bit registers by same mechanism, it is perfectly fine.
a = ((tUI16)REG_1); // REG_1 is pointer to 16 bit register ---> Red error b = ((tUI32)REG_2); // REG_2 is pointer to 32 bit register ---> No error
I need to take care of these, since they are causing red warnings(NTL) in the loop they are implemented in. How shall I proceed?

Hello Binod,
are REG_1 and REG_2 really pointers? Because here you are casting these pointers to integers. Can you tell me the definition of REG_1 and REG_2?
