In SX Microcontrollers, SX/B Compiler and SX-Key Tool, Peter Van der Zee wrote: Hi Shane; All JT said above is true, but in addition, the method of accessing the MODE (M) register is different, hence setting I/O directions would be affected. You cannot write a literal directly to the M register, you must go through the W register. Furthermore, the M codes are different for the SX 48/52. Hope this helps, Cheers, Peter (pjv) ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=82511#m82568 Need assistance?
