Many thanks all.

In general terms this is what I'll do.

In the ISR()

	if( ReadCurrent() > CurrentLimit )
	{ //depending on speed value,=20
	  // overload could last up to a mS ... should be ok...
		RedLED =3D 1 ;
		++OverCurrent ;
		CCPR1L =3D 1 ; // the next duty cycle is about 1%
	}
	else
	{ // if there had been an over current then reset to normal
		RedLED =3D 0 ;
		OverCurrent =3D 0 ;
		CCPR1L =3D SpeedValue ;
	}


In the SetMotorSpeed() routine (comes here regular and often)

	if( OverCurrent =3D=3D 0 )
	{
		CCPR1L =3D SpeedValue ;
	}
	else
	{

		// decide what to do about it
		// ? check number of times ?
	}
