** ===================================================================

** Method : Cap1_Disable (component Capture)

** Description :

** This method disables the component - it stops the capture. No

** Parameters : None

** Returns :

** --- - Error code, possible codes:

** ERR_OK - OK

** ERR_SPEED - This device does not work in

** the active speed mode

** ===================================================================

byte Cap1_Disable(void)

TIE_C0I = 0U; /* Disable interrupt */

TSCR2_TOI = 0U; /* Disable overflow interrupt */

/* TCTL4: EDG0B=0,EDG0A=0 */

TCTL4 &= (uint8_t)~(uint8_t)0x03U; /* Disable capture function */

}

return ERR_OK; /* OK */

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,
Zhang Jun

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.

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,

Zhang Jun

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