What does representation in 0*0x100u mean in C . If it end with "b" . I know its binary . What is "u"
 

Are you using TI's code composer studio? I didn't know you could do that in it.

The 'u' at the end will be specifying that the literal value (0x100) is to be stored as an unsigned integer. I have seen that use in C# programming.

It is the 0x preceding the literal value that specifies hexadecimal, 0b preceding it would indicate binary (as 0b100, or possibly 0b100u to also indicate unsigned int).

Yes in CCS only . MSP header files has such values . Yep it is unsigned hex value . Thanks for the reply
