6.11.4
Diagnosis of CPS OUTA, B, C, D when configured as single low side
power stages
For the low side the diagnosis is the same as LSd (see Section 6.9).
Each channel locally detects and writes its own fault or no-fault condition (codified on 2 bit
according to Table 27: Fault encoding condition).
Short circuit to battery or overcurrent for all the outputs during ON condition.
Open load or short to GND during OFF condition.
The faults are latched and reset at every Read Diag operation.
In OFF condition the first fault detected is latched and can be overwritten only by the ON
condition fault.
