一路PWM波控制直流电机问题

请问程序里的PTP_PTP6，PTP_PTP7是什么作用
//---------电机正转---------
void PWMoutVec(int Velocity)
{
if(Velocity>667) Velocity=667;
PTP_PTP6=1;
PTP_PTP7=0;
PWMPER45 = 667;
PWMDTY45 = Velocity;
}
//---------能耗制动---------
void PWMoutStopVec(int Velocity)
{
PTP_PTP6=1;
PTP_PTP7=1;
if(Velocity>667) Velocity=667;
PWMPER45 = 667;
PWMDTY45 =0;
}
//---------电机反转---------
void PWMoutREVec(int Velocity)
{
PTP_PTP6=0;
PTP_PTP7=1;
if(Velocity>667) Velocity=667;
PWMPER45 = 667;
PWMDTY45 =Velocity;
}
