What does `u` at the end of a number mean?

Question

I know 0xFF is hex. What is u?

#define PDL_ADC_10_MODE_SINGLE 0x00000001u

@CuriousSid Single letter suffixes are sometimes hard to search on Google. — fuz, Mar 27 '13 at 08:57

When ending a number literal, it means that the number is unsigned
