Smart 16-Channel Low-Side Switch

Control of the Device

6.2.1

Diagnosis Read-out options

By means of the control byte it is possible either to:

1. control the outputs according to the data byte, as well as being able to read the diagnostic information (two bits

per channel)

2. or purely get diagnostic information without changing the state of the outputs

3. or read back the parallel inputs plus a simple diagnosis (one bit per channel)

4. or SPI “Echo Function” as a diagnosis of proper SPI function.

Diagnosis Read-Out Option 1): Serial Control of Outputs

SI information: OR-operation valid for channels 1 to 8

SO: 16 bit diagnosis for channels 1 to 8 performed during next chip select cycle

SI information: OR-operation valid for channels 9 to 16

SO: 16 bit diagnosis for channels 9 to 16 performed during next chip select cycle

SI information: AND-operation valid for channels 1 to 8

SO: 16 bit diagnosis for channels 1 to 8 performed during next chip select cycle

SI information: AND-operation valid for channels 9 to 16

SO: 16 bit diagnosis for channels 9 to 16 performed during next chip select cycle
