Hi.. I have a problem with the xc167ci. Its I/O-Pins toggle too slowly. If I have e.g. pin 4^0 toggeling, it only works with 2,85 MHz instead of 40 MHz (system clock). I use the following sourcecode: while(1) { P9_0 = 0; P9_0 = 1; } In EBC-Mode the pins are pretty fast, they work on a 25 ns basis. Why does that not work on normal I/O-Pin operations? Thanks, Erwin
