Counter stops once execution is suspended, never resumes

So I'm using KDS Version: 3.2.0 on a Windows 7 Pro PC.


I've simplified my code to:


int main(void) {
  /* Init board hardware. */




  /* Add your code here */


  for(;;) { /* Infinite loop to avoid leaving the main function */
    __asm("NOP"); /* something to use as a breakpoint stop while looping */


void InitFTM1()
    SIM_SCGC6 |= (1<<FTM1);                    // Enable Power to FTM1
    FTM1_MODE = (1<<WPDIS) + (1<<FTMEN);    // FTM not old TPM mode
    FTM1_MOD = 75*100-1;                    // 75 Mhz clock  100 us clock period
    FTM1_SC = (1<<CLKS);                    // use system clock


When I suspend execution I observe the following hex register values:

FTM1_SC      88

FTM1_CNT      varies

FTM1_MOD   1db4



When I resume and suspend (multiple times) the FTM1_CNT is always the same as the first time I suspended.


I want it to resume counting.  What am I doing wrong?
