5.6.4 Resolver with Mirror Out
When using a resolver, a TTL encoder signal can be generated to mirror the resolver signal. The mirroring enables transferring the
shaft position to other devices for monitoring, or further control. The encoder output signal can be scaled by defining the number
of pulses representing 1 rotation of the resolver.
