5.5.2
The SPI of TLE8104E is daisy chain capable. In this configuration several devices are activated by the same signal
CS. The SI line of one device is connected with the SO line of another device (see
chain. The ends of the chain are connected with the output and input of the master device, SO and SI respectively.
The master device provides the master clock SCLK, which is connected to the SCLK line of each device in the
chain.
Figure 11
In the SPI block of each device, there is one shift register where one bit from SI line is shifted in each SCLK. The
bit shifted out can be seen at SO. After 8 SCLK cycles, the data transfer for one device has been finished. In single
chip configuration, the CS line must go high to make the device accept the transferred data. In daisy chain
configuration the data shifted out at device 1 has been shifted in to device 2. When using three TLE8104E devices
in daisy chain, three times 8 bits have to be shifted through the devices. After that, the CS line must go high (see
