Global Error Flag

A logic OR combination between Global Error Flag (GEF) and the signal present on SDI is reported on SDO

between a CSN falling edge and the first SCLK rising edge (Figure 13). GEF is set if a fault condition is detected

or if the device comes from a Power On Reset (POR).

Note:

The SDI pin of all devices in daisy chain or non daisy chain mode must be Low at the beginning of the

SPI frame (between the CSN falling edge and the first SCLK rising edge).

It is possible to check if the TLE94112ES has detected a fault by reading the GEF without SPI clock pulse

(Figure 16).
