6.1
Below are examples of the different SPI command words and the resulting behavior of the output channels and
Seiral Output pin.
6.1.1
The contents of the diagnosis register will be returned during the next SPI access. This command is only active
once unless the next control command is again “Diagnosis only” (see
In the example shown in
load for channel 2 (01), over load / over temperature for channel 3 (10) and normal operation for channel 4 (11).

6.1.2
The first four bits of SO during the next SPI access give the state of the parallel inputs, denoted by INn. The
second four-bit word fed out at SO contains 1-bit diagnosis information of the output (1 = no fault, 0 = fault),
denoted by Fn (see
Figure 15
6.1.3
This function can be used to check the proper function of the serial interface. This command connects directly the
SI to the SO during the next CS period. This internal connection is only active once unless the next control
command is again “Echo function of SPI” (see
