Table 5
If the TLE6240GP is used as bare die in a hybrid application, it is necessary to know if proper connections exist
between the µC-port and parallel inputs. By entering ‘HHLL’ as the control word, the first eight bits of the SO give
the state of the parallel inputs, depending on the µC signals. By comparing the IN-bits with the corresponding
µC-port signal, the necessary connection between the µC and the TLE6240GP can be verified - i.e. ‘read back of
the inputs’.
The second 8-bits fed out at the serial output contains ‘1-bit’ fault information of the outputs (H = no fault, L = fault).
In the expression given below for the output byte, ‘FX’ is the fault bit for channel X.
