6.4.4.1

Previous Address SOA4:SOA0 = A1A0000 (STATR_s)

The returned data OD8 reports logic [1] in case of previous Power ON Reset condition (VSUPPLY(POR)). This bit is only reset by

a read operation.

Bits OD7:OD0 reflect the current state of the Fault register (FLTR) corresponding to the output previously selected with the bits

SOA4:SOA3 = A1A0 (Table 23).

• OC_s: overcurrent fault detection for a selected output,

• SC_s: severe short-circuit fault detection for a selected output,

• OS_s: output shorted to VPWR fault detection for a selected output,

• OLOFF_s: OpenLoad in OFF state fault detection for a selected output,

• OLON_s: OpenLoad in ON state fault detection (depending on current level threshold: bulb or LED) for a selected output,

• OV: overvoltage fault detection,

• UV: undervoltage fault detection

• POR: power on reset detection.

The FSB pin reports all faults. For latched faults, this pin is reset by a new Switch OFF command (toggling fault_control signal).

6.4.4.2

Previous Address SOA4:SOA0 = A1A0001 (Pwmr_s)

The returned data contains the programmed values in the PWMR register for the output selected with A1A0.

6.4.4.3

Previous Address SOA4:SOA0 = A1A0010 (confr0_s)

The returned data contains the programmed values in the CONFR0 register for the output selected with A1A0.

6.4.4.4

Previous Address SOA4:SOA0 = A1A0011 (confr1_s)

The returned data contains the programmed values in the CONFR1 register for the output selected with A1A0.

6.4.4.5

Previous Address SOA4:SOA0 = A1A0100 (ocr_s)

The returned data contains the programmed values in the OCR register for the output selected with A1A0.

6.4.4.6

Previous Address SOA4:SOA0 = 00101 (gcr)

The returned data contains the programmed values in the GCR register.

6.4.4.7

Previous Address SOA4:SOA0 = 00111 (diagr0)

The returned data OD2 reports logic [1] in case of PWM clock on IN0 pin is out of specified frequency range.

The returned data OD1 reports logic [1] in case of calibration failure.

The returned data OD0 reports logic [1] in case of overtemperature prewarning (temperature of GND flag is above TOTWAR).

6.4.4.8

Previous Address SOA4:SOA0 = 01111 (diagr1)

The returned data OD4: OD1 report in real time the state of the direct input IN[3:0].

The OD0 indicates if the watchdog is enabled (set to logic [1]) or not (set to logic [0]). OD4:OD1 report the output state in case

of Fail-safe state due to watchdog time-out as explained in the following Table 24.
