What mechanism is it that causes the SMCLK to stop when Code Composer Studio hits a breakpoint or you use the "pause" button? I have BOTH the MCLK and SMCLK set to be driven by DCO/1, and I have ACLK, MCLK, and SMCLK directed to device pins (P1.5, P1.2, and P1.6, respectively) but whenever Code Composer Studio hits a breakpoint or I use the "pause" button, I see that only ACLK and MCLK continue to run, while SMCLK stops. What is it that causes this behavior?
