byte Cap1_Enable(void)

{

  if (!EnUser) {                       /* Is the device disabled by user? */

    EnUser = TRUE;                     /* If yes then set the flag "device enabled" */

    TCTL4 |= 0x03U;                    /* Enable capture function */

  }

Hi KDN,

I am not sure if i understand your question.

when you add Capture component to a project,  Capture mode is enabled by default.

when you want disable capture mode, you can execute

Cap1_Disable()

in your code .

when you want enable it again, you execute

Cap1_Enable()

does it make sense?

Have a great day,

How can I set timer in interrupt for 10m sec

[ZhangJennie]

hi KDN

I am afraid this mc9s12xhz chip doesn't support FreeCntr component.

Please use TimerInt component to set 10ms interrupt

can this help?

Have a great day,

If I run API periodic interrupt timer my Input capture mode not work

[kdn]

This FreeCntr component is shared with input capture mode time , I need separate timer

[kdn]

I have connected 3 PWM channel On input capture pin for reading duty cycle of signal, I want to read them one by one in interrupt mode.
