For targets which assign u8 by an 16Bit type, the definition of macros must changed to functions. 23.02.2005 r.d.: Functions included for extended data types such as UNSIGNED24, UNSIGNED40, ... 13.06.2006 d.k.: Extended the interface for EPL with the different functions for little endian and big endian ****************************************************************************/ #ifndef _EPLAMI_H_ #define _EPLAMI_H_ //--------------------------------------------------------------------------- // types //--------------------------------------------------------------------------- //--------------------------------------------------------------------------- // Prototypen //--------------------------------------------------------------------------- #ifdef __cplusplus extern "C" { #endif //--------------------------------------------------------------------------- // // write functions // // To save code space the function AmiSetByte is replaced by // an macro. // void AmiSetByte (void * pAddr_p, u8 bByteVal_p);
