SSC Data Transfer

The SSC data transfer is word-aligned. The following transfer words are possible:

•

Command Word (to access and change operating modes of the TLE5012)

•

Data Words (any data transferred in any direction)

•

Safety Word (confirms the data transfer and provide status information)

Command Word

The TLE5012 is controlled by a Command Word. It is sent first at the start of every data transmission. The structure

of the Command Word is shown in Table 15, where the update (UPD) bit allows access to current or updated

values. If an update command is issued and UPD is set, the immediate values are stored in the update buffer

simultaneously. This enables a snapshot of all necessary system parameters at the same time. Bits with an update

buffer are marked by an “u” in the bit type in the register description.
