3FG_PA7 output function

The 3FG_PA7 pin has a different function according toTable 13.

When the 3FG function is selected the 3FG_PA7 pin works as the open-drain output (see

Figure 17). The 3FG signal is synthesized from the Hall-effect sensors feedback applied to

the op amp inputs.

The analog output of the op amp is converted into a logic signal through internal

comparators (Vref = VDD/2) and provided to Hall decoding logic.

The 3FG resulting output signal is an exclusive-OR function of the three Hall sensors (see

Table 14).
