Can we use BIT() macro in the assembler code too ?

Probably, but just following convention in the rest of the file. Do we want to change from existing code?

Agreed, we should follow the existing style (and I'm not 100% sure I like using BIT() in asm files).

OK. Will drop this feedback about BIT() macro if I have to do a v2.

Fine by me
