MSP430g2553 clock calibrations

Other Parts Discussed in Thread: MSP430G2553

Hi everyone;

Lately I've developed a need to increase the clock speed of my msp430g2553.  I have been using the following code to run the clock at 1MHz.  

void ConfigClocks(){	
		
	BCSCTL1 =CALBC1_1MHZ;							//set range
	DCOCTL = CALDCO_1MHZ;							//set DCO step+ modulation
	BCSCTL3 |= LFXT1S_2;							//LFXT1 = VLO 
	IFG1 &= ~OFIFG;									//clear OSCFault flag
	BCSCTL2 |= SELM_0 +DIVM_3 +DIVS_3;				//MCLK = DCO/8, SMCLK = DCO/8
	
}

In order to increase the clock speed I adjusted all of the clock speeds from 1MHz to 8 MHz which resulted in the following final draft of code

void ConfigClocks(){	
		
	BCSCTL1 =CALBC1_8MHZ;							//set range
	DCOCTL = CALDCO_8MHZ;							//set DCO step+ modulation
	BCSCTL3 |= LFXT1S_2;							//LFXT1 = VLO 
	IFG1 &= ~OFIFG;									//clear OSCFault flag
	BCSCTL2 |= SELM_0 +DIVM_3 +DIVS_3;				//MCLK = DCO/8, SMCLK = DCO/8
	
}

I looked in the header file "msp430g2553.h" and found that there are definitions for CALBC1_8MHz and CALDCO_8MHz, but I keep getting the following errors,

unresolved symbol CALBC1_8MHZ, first referenced in ./blinker.obj

and

unresolved symbol CALDCO_8MHZ, first referenced in ./blinker.obj

can anyone tell me why these symbols are still unresolved even though they are defined in the header file

"msp430g2553.h"?

Thanks:

Greg
