You can handle each IO pin by ByteIO bean as well as in BitsIO bean. <BR /><BR />Generally if you need to handle a whole port (8-bit input/output) it is recommended to select ByteIO bean instead of BitsIO bean and it is recommended to select the BitsIO bean for utilization as a two- to seven-bit input/output. ByteIO bean has more optimized code of some methods than BitsIO bean when using for whole 8 pin port. <BR /><BR />best regards<BR />Vojtech Filip<BR />Processor Expert Support Team<BR />UNIS<BR /><DIV></DIV></BODY></HTML> Tue, 17 Feb 2009 22:34:08 GMT https://community.nxp.com/t5/CodeWarrior-for-MCU/PE-BitsIo-and-ByteIo/m-p/153664#M3819 ProcessorExpert 2009-02-17T22:34:08Z
