TLE94104EP

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 16).

Figure 16 SPI with independent slave configuration

Each SPI communication starts with one address byte followed by one data byte (Figure 17).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 TLE94104EP.
