The SPI of TLE7237SL provides diagnosis information about the device and about the load. The diagnosis
information of the protective functions of channel n is latched in the diagnosis flags Dn. It is cleared by the SPI
command CMD.CPL = 1. The CPL command clears itself with the next valid SPI communication frame.
The open load diagnosis of channel n is latched in the diagnosis flag OLn. This flag is cleared by reading the
according diagnosis register.
Following table shows possible failure modes and the according protective and diagnostic action.
