    CY8C22545 set to work on 3.3V 24mhz fail

    teddy.wolf

      hi,

         

      I set CY8C22545 work on 3.3V 24mhz  in psoc designer 5.1 sp2.1.

         

      I generate the code and compile. There is a error in boot.asm.

         

      I copy some code from boot.asm file

         

      IF (POWER_SETTING & POWER_SET_3V3)  ; 3.3V Operation?
       IF ( POWER_SETTING & POWER_SET_SLOW_IMO)      ; *** SLIMO = 6MHZ, Do Nothing ***
       ELSE
         IF (CPU_CLOCK_JUST ^ OSC_CR0_CPU_24MHz) ; Not 24 MHz, Do Nothing...
         ELSE      ; Otherwise, 24 MHz is selected... raise error
       ERROR_PSoC SEE COMMENTS   ; Error - cannot use 24 MHz w/ 3.3V operation (Clock <= 12 MHz)
         ENDIF
       ENDIF
      ELSE
       

         

      It shows that "cannot use 24 MHz w/ 3.3V operation (Clock <= 12 MHz)"

         

      But I search the Technical Reference Manul, i found set CY8C22545 work on 3.3V 24mhz  is ok.

         

      please help me how to set CY8C22545 work on 3.3v and RUN on 12MHZ or 24MHZ.

         

      THANKS.
