hello
I am working on arm cortex m3 and I can see 0xFFFFFFu1 in library . So what is the meaning of u ?
thanks for your help

Unsigned. Maybe unsigned long.

without checking..... unsigned long ?

thanks . I have one more question.
what is the value of this unsigned value ?

by u1 you probably meant ul which stands for unsigned long as mentioned
