POSITION

#define POSITION

(

X

)

(1U << (X))

Define a constant bit at position X, starting from index 0.

Parameters

X	An unsigned integer constant representing the position of the bit, starting from index 0.

Warning

The constant must be specified using an unsigned integer litteral in uppercase. e.g. POSITION(2U) This is to make static analyzers not complain about using a shift operator with an unsigned value.
