Re: error #20: identifier "TA0CCTL0_bit" is undefined....help on code composer

I am using the msp430g2553....

I have enclosed the complete program below.....I believe the original software used iar to compile using "io430.h" header which I cannot use in code composer. I am new at this and am struggling with final project for a class. I have two marked lines with errors with ****** after //....

Thanks Ted
