Description
Read-only registers
Read and write registers
Update buffer for this bit is present. If an update is issued and the Update-
Register Access bit (UPD in Command Word) is set, the immediate values
are stored in this update buffer simultaneously. This allows a snapshot of all
necessary system parameters at the same time.

The data communication via SSC interface has the following characteristics:
• The data transmission order is Most-Significant Bit (MSB) first, Last-Significant Bit (LSB) last.
• Data is put on the data line with the rising edge on SCK and read with the falling edge on SCK.
• The SSC Interface is word-aligned. All functions are activated after each transmitted word.
• After every data transfer with ND ≥ 1, the 16-bit Safety Word is appended by the TLI5012B E1000.
• A “high” condition on the Chip Select pin (CSQ) of the selected TLI5012B E1000 interrupts the transfer
immediately. The CRC calculator is automatically reset.
• After changing the data direction, a delay t_{wr_delay} (see Table 4-15) has to be implemented before continuing
the data transfer. This is necessary for internal register access.
• If in the Command Word the number of data is greater than 1 (ND > 1), then a corresponding number of
consecutive registers is read, starting at the address given by ADDR.
