4.3
The SPI of SPIDER - TLE7232G provides diagnosis information about the device and
about the load. There are following diagnosis flags implemented:
• The diagnosis information of the protective functions (flags CLn and Tn) of channel n
• The open load diagnosis of channel n is latched in the diagnosis flag OLn.
• The short to gnd monitor information of channel n is latched in the diagnosis flag SGn.
All flags are cleared after a successful SPI transmission.
There is an output state monitor implemented in the device that indicates the switch state
of the device in register STA. Depending on the voltage level at input pin and protective
functions the bits are high or low.

is latched in the diagnosis flag Pn.
