48 * Stringize a preprocessing token, this token being allowed to be \#defined.
50 * May be used only within macros with the token passed as an argument if the token is \#defined.
52 * For example, writing STRINGZ(PIN) within a macro \#defined by PIN_NAME(PIN)
53 * and invoked as PIN_NAME(PIN0) with PIN0 \#defined as A0 is equivalent to
58 /*! \brief Absolute stringize.
60 * Stringize a preprocessing token, this token being allowed to be \#defined.
62 * No restriction of use if the token is \#defined.
64 * For example, writing ASTRINGZ(PIN0) anywhere with PIN0 \#defined as A0 is
65 * equivalent to writing "A0".
