PWM generation using software by UCD3138

Hi All,

I am using UCD3138, and I  have to use TCAP pin to generate PWM signals(all of my other DPWM modules as well as PWM outputs are busy) to control  a fan. At this point, I just want to make sure that I can generate some PWM signals using software on pin TCAP. As I am a hardware engineer, I am not so familiar with software.I came up with the following codes: Can you please let me know if it will be giving me PWM signals on TCAP? (Forget about the duty cycle and frequency at this point):

   for(;;)
    {
// Set pin TCAP to 1
  MiscAnalogRegs.GLBIOEN.bit.TMR_CAP_IO_EN = 1; // enable TCAP as GPIO
  MiscAnalogRegs.GLBIOOE.bit.TMR_CAP_IO_OE = 1; // make it output
  MiscAnalogRegs.GLBIOVAL.bit.TMR_CAP_IO_VALUE = 1;  // set output to high

// Set Timer3 to generate delay=duty cycle

   TimerRegs.T16PWM3CMP0DAT.bit.CMP_DAT = 1587; // Value to reset the counter and specify duty cycle

   TimerRegs.T16PWM3CMPCTRL.bit.CMP0_INT_ENA = 1; // interrupt when reset

   TimerRegs.T16PWM3CNTCTRL.bit.CMP_RESET_ENA = 1; // enable reset by comp0

    TimerRegs.T16PWM3CNTCTRL.bit.SW_RESET = 1; // allow counter to run
  TimerRegs.T16PWM3CMPCTRL.all |= 3; // clear interrupt flag
 
  // Set pin TCAP to 0
   MiscAnalogRegs.GLBIOVAL.bit.TMR_CAP_IO_VALUE = 0; // set output to high
 
// Set Timer3 to generate delay=off-time
    TimerRegs.T16PWM3CMP0DAT.bit.CMP_DAT = 1587; // Value to reset the counter and specify duty cycle

    TimerRegs.T16PWM3CMPCTRL.bit.CMP0_INT_ENA = 1; // interrupt when reset

     TimerRegs.T16PWM3CNTCTRL.bit.CMP_RESET_ENA = 1; // enable reset by comp0

    TimerRegs.T16PWM3CNTCTRL.bit.SW_RESET = 1; // allow counter to run

    TimerRegs.T16PWM3CMPCTRL.all |= 3;  // clear interrupt flag

   }

Thanks all in advance
