011 — Output Configuration Register (CONFR1_s)
The CONFR1_s register allows the MCU to configure corresponding output fault management through the SPI. Each output “s”
is independently selected for configuration, based on the state of the D14 : D13 bits (Table 12).
A logic [1] on bit D6 (RETRY_unlimited_s) disables the autoretry counter for the selected output, the default value [1] corresponds
to enable auto-retry feature without time limitation.
A logic [1] on bit D5 (RETRY_dis_s) disables the auto-retry for the selected output, the default value [0] corresponds to enable
this feature.
A logic [1] on bit D4 (OS_dis_s) disables the output hard shorted to V
PWR
protection for the selected output, the default value [0]
corresponds to enable this feature.
A logic [1] on bit D3 (OLON_dis_s) disables the ON output OpenLoad detection for the selected output, the default value [0]
corresponds to enable this feature (
Table 14).
A logic [1] on bit D2 (OLOFF_dis_s) disables the OFF output OpenLoad detection for the selected output, the default value [0]
corresponds to enable this feature.
A logic [1] on bit D1 (OLLED_en_s) enables the ON output OpenLoad detection for LEDs for the selected output, the default value
[0] corresponds to ON output OpenLoad detection is set for bulbs (Table 14).
A logic [1] on bit D0 (CSNS_ratio_s) selects the high ratio on the CSNS pin for the corresponding output. The default value [0] is
the low ratio (Table 15).

100 — Output Overcurrent Register (OCR)
The OCR_s register allows the MCU to configure corresponding output overcurrent protection through the SPI. Each output “s”
is independently selected for configuration based on the state of the D14
: D13 bits (Table 12).
A logic [1] on bit D8 (Xenon_s) disables enables the Xenon 55 W or 28 W bulb overcurrent profile, as described Figure 14.
