Macros end by 'U' in XSDK

Jump to solution

Hi ,

While I was checking IOMODULE Macros in xparameters.h file ,

I found many Macros ending with U , like these below:

#define XPAR_IOMODULE_0_USE_GPI1 1U
#define XPAR_IOMODULE_0_GPI1_SIZE 32U

In fact I looked through  pg111 and I knew the purpose of each these above Macros, but the "U" doesn't not mentioned in the manual .

For what stand this "U" ?

Looking forward your explanation.

Thanks in advance
