Which header file to use with Silabs EFM8LB12F64

Dear all,

Would you help me to identify which header file to use with Silabs EFM8LB12F64E?

I already tried to compile a very simple program , but, failed.

 #include <SI_EFM8LB1_Register_Enums.h>

 sbit LED_Green = P1^4;

 sbit LED_Blue = P1^5;

 sbit LED_Red = P1^6;

 sbit PB0 = P0^2; //Push Button 0

 sbit PB1 = P0^3; //Push Button 1

  MCU_init(){

 // TO disable watchdog timer      do following

   WDTCN = 0xDE;

   WDTCN = 0xAD;

 //now, watchdog disabled

    CLKSEL = 0x88;     // Set system clock to 24.5 MHz

 //assign inputs

    P0MDIN=P0MDIN | 0x0C; //set bit 2 and 3 of P0 for DI

    P0MDOUT=P0MDOUT & 0xF3; // clear bit 2 and 3  of P0 for Open Drain

    P0^2 = 1;

    P0^3 = 1;

 //assign outputs

    P1MDIN=P1MDIN | 0x70; //set bit 4, 5 and 6 of P1 for DO

    P1MDOUT=P1MDOUT | 0x70; // set bit 4, 5 and 6 of P1 for Push-Pull

 }

 main()

 {

   MCU_init();

   while(1){

     if ( PB0 ^ PB1 )

      {

         LED_Green=1 ;

      }

           else

           {

           LED_Blue = PB0 ;

           LED_Red = PB1;

           }

           }

   }

Build operation resulted in following errors :

It is obvious that the compiler cannot understand register names.

Please, help me to identify.

Best regards!
