Position Queries
The following allow a host controller to query the TDD2 for position information.
7.8.1
Displayed Position Query
Reads the currently displayed position. This position is calculated in the same manner as the
displayed position, and takes into account the configured display mode (absolute, gap, or relative). If a
position error is detected, either “0NOXDCR” (no transducer detected) or “0NOMAG” (no magnet
detected) is returned. Otherwise, the position is returned.
