Byte is sent in a data transfer with ND = 0 (e.g. Update Command).
Byte (bits [3..0], low nibble). In this way, broadcast messages also produce individual feedback of every
selected slave. This is necessary to differentiate among the individual TLE5011 slave responses, because the
CRC Byte is written by both TLE5011 units in parallel.
the dedicated bit in the Slave-Active Byte (bits [7..4], high nibble) low. If not, the bit in the high nibble remains 1.
can the transfer proceed. Furthermore, this command is added to the CRC calculation of the following
SSC transfer.
This command transfers the present immediate values of each register to the update register. After an Update
Command, the CS line does not need to be set and reset again.
The TLE5011 always sends logical 1 and all following sent bits from the SSC Master are ignored (TLE5011 is
in Idle mode). To enable data transfers again, the Chip Select pin (CS) of the TLE5011 must be deselected for
CS
update registers are present. Other registers are accessed directly.
The data transmission order is “Most Significant Bit (MSB) first”.
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 Byte-aligned. All functions are activated after each transmitted Byte.
A “high” condition on the negated Chip Select pin (CS) of the selected TLE5011 interrupts the transfer
Every access to the TLE5011 with the number of data (ND) ≥ 1 is performed with address auto-increment.
After an auto-increment overflow, the addresses begin from 00
For every data transfer with ND ≥ 1, an 8-bit CRC Byte will be appended by the selected TLE5011. No CRC
After the CRC Byte is sent, the bit represented by S_NO is pulled low by the selected slave in the Slave-Active-
If the CRC Byte on the bus is the same as the internally generated CRC of each TLE5011, each slave pulls
A write command to address 00
A command of 0000_0000 is called Update Command.
The transfer ends after the CRC and Slave-active Byte have been sent.
If the Update Mode is selected (CTRL register, UR = 1), all accesses are performed to update registers where
