Speed Inputs
Can be used in two modes : Hall or Magnetic.
In Hall mode a 4700 ohm pullup resistor is connected to 5V and the trigger
levels are fixed.
In Magnetic mode the pullup resistor is disengaged and the trigger levels can
be varied depending on the input frequency.
Note that the Hall and Magnetic modes must be activated in pairs, ie inputs 1
& 2 must have the same mode and level settings, similarly inputs 3 & 4 must
have the same mode and level settings.
