In SX Microcontrollers, SX/B Compiler and SX-Key Tool, Peter Van der Zee wrote: Hi Bill; As ROBOT said, without your code posted it is difficult for any of us to help much; however, if it is I/O that is troubling you in moving from the SX28 to the SX48 then I suspect you have overlooked the differences in the M codes for setting up the direction (and other) I/O registers. The SX28 uses M=$0F and the SX48 uses M=$1F.
