4.3.4.1

Error-Flag

In addition to the 16 bits transferred from the TLE 7201R to the SPI master, an additional

Error Flag (EF) is transmitted at the DO pin. The EF status is shown on the DO pin after

CSN H->L, before the first rising edge at CLK, as shown in Figure 6.

The Error flag is set to H if any of the Status Registers contains an error message (i.e.

EF = EF_00 or EF_01 or EF_10 or EF_11)
