I'm not sure if the index HAL pin is supposed to be a copy of the 
hardware index pin or not - that pin isn't part of the canonical encoder 
interface and does whatever the driver writer had in mind a the time.

The index-enable HAL pin is bidirectional - you need to set it true, 
then the driver will set it false (and reset the counter) on the next 
index pulse.  If index-enable is false, the driver does nothing at all 
when it sees an index pulse.
