The Incremental Interface (IIF) uses an up/down counter of a microcontroller for the angle transmission. The
synchronization is done by the parallel active SSC-Interface. The angle value read out by the SSC-Interface can
be compared with the stored counter value. In case of a non-synchronization, the microcontroller add the
difference to the actual counter value to synchronize the TLE5012 with the microcontroller. The resolution of the
IIF can be selected within the interface mode4 register (MOD_4) under IFAB_RES.
A/B Mode
The phase shift between phase A and B indicates a clockwise (B follows A) or a counterclockwise (A follows B)
rotation of the magnet.
