It isn't in Texas Instruments TMS320. I will quote from http://processors.wiki.ti.com/index.php/C89_Support_in_TI_Compilers http://processors.wiki.ti.com/index.php/C89_Support_in_TI_Co... > The C standard uses the term byte to mean the minimum addressable unit in the implementation, which is char, which means a byte on these targets is 16 bits. This is in conflict with the widespread use of byte to mean 8 bits exactly. This is an unfortunate disagreement between C terminology and widespread industry terminology that TI can't do anything about.
