Code evaluation board drv8711 evm (timer using)

Other Parts Discussed in Thread: DRV8711

// Pulse Timer Output [ OPCODE = 0x0F ] [Timer Used] [ Pulse Length Hi ] [ Pulse Length Lo ] [ Not Used ]

      case (PULSE_TMR):
        TBCTL &= ~TB_CNTL_08;                //Configure Timer to run up to FFFF (16 bit FRC)
        switch (SerialBuffer[1])
        {
        case 1:
            TBCCTL1 &= 0xFF1F;                                          // Clear OUTMODx bits; 3 MSB on lower byte; Timer configured to output mode
            TBCCTL1 |= TB_OUT_HIGH;                                     //Set the output (pulse start)
            TBCCTL1 |= TB_OUTMOD_RESET;                                 //Configure the timer to reset
            TBCCR1 = TBR + ((SerialBuffer[2] * 256) + SerialBuffer[3]); //Configure the pulse reset time (pulse end)
          break;
        }
        break;

This  a piece of  code  of   evm drv8711  stepper motor , my  question is wich  8 bit  value  must  insert in the [Timer Used]??

I  suppose that timer is timer  B , but  i dont know  if must insert the address  of  control  register  timer  B (TBCTL) or other value? Can  please help me , i would  like  know  the  value   to insert.

Thanks
