Hi i'm using UV3 for Infineon XC164CS-DAvE project.i'm facing a problem while debugging the DAvE generated files. During the dubugging, PLL Control register is added with default value..but while the instruction executes for loading this register PLLCON with 0x7814,it hangs and giving the msg :" Connection to the TARGET SYSTEM LOST". here is my config settings. Configuration of the System Clock: -VCO clock used, input clock is connected -input frequency is 8 MHz -VCO output frequency 100 .. 150 MHz -system clock is 20 MHz fin = 4Mhz fpll =20MHz fvco =100MHz fcpu =20MHz Plz,let me know if anyone has a solution.
