Serial Peripheral Interface (SPI)
7.2
SPI with independent slave configuration
In an independent slave configuration, the microcontroller controls the CSN of each slave individually
(Figure 18).

Figure 18 SPI with independent slave configuration
Each SPI communication starts with one address byte followed by one data byte (Figure 19).The LSB of the
data byte must be set to ‘1’.The address bytes specifies:
• the type of operation: READ ONLY (OP bit =0) or READ/ WRITE (OP bit = 1) of the configuration bits, and
READ ONLY (OP bit =0)or READ & CLEAR (OP bit = 1) of the status bits.
• The target register address (A[6:2])
The Last Address Byte Token bit (LABT, Bit1 of the address byte) must be set to 1, as no daisy chain
configuration is used.
While the microcontroller sends the address byte on SDI, SDO shifts out GEF and the Global Status Register.
A further data byte (Bit15...8) is allocated to either configure the half-bridges or retrieve status information of
the TLE94106EL.
