3.2 Group Description

3.2.6 Reset Operation

A total reset is initiated by a write access to the Group Reset Register. Depending on the state of the quadrature signals, the counters can be cleared, or set to +1 or -1. To avoid this count error (+1 or -1) after the reset, the Ua1n and the Ua2n inputs should be held to the values indicated in table 3-1 during and just after the write access. It is recommended to check if the counters are cleared after the group reset.
