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
