Forum Post: MSP430F5438 Capture Mode

Hello I am trying to use the capture mode Main Clk Source: SMCLK Internal Signal: ACLK The problem is it keeps getting stuck in the while loop. Can you please help me out TBCTL = TBSSEL_2 + MC_2 + TBCLR; //MC_2 | TBSSEL_2, SMCLK, CONT Mode TB0CCTL6 = CM_1 | CAP | CCIS_1; //TB0CCR6 = 0x32; while(1) { while(!(TB0CCTL6 & CCIFG)); //gets stuck here TB0CCTL6 &= ~CCIFG; }
