41 / 69 page  DocID025319 Rev 3 41/69 L99LD01 SPI functional description 68 3.6 Status registers Status registers 1 Address: 0x04h Type: R/C 15 14 13 12 11 10 98765 43210 Reserved Vs_Ov Vs_Uv Led_Oc Led_Ov WD_fail — R(1) R R(1) R/C(2) R R/C(2) 1. “Read only”, real time bit. 2. These bits are latched until a “Read and Clear” access. Bit [15:13] Reserved Bit [12] Lmode_Err: this bit is set if a mismatch between the signal on LMODE pin and VLED pin is detected. Bit [11] Vs_Ov: is set if an overvoltage event at the supply line is detected Bit [10] Vs_Uv: is set if an under voltage event at the supply line is detected Bit [9] Led_Temp_Warn: temperature warning for the LED Bit [8] Led_Oc: Is set if an over current event across the LED chain is detected Bit [7] Led_Ov: is set if an overvoltage event across the LED chain is detected Bit [6] Vcc1_Off: when set, this bit indicated that VCC1 is off Bit [5] Vcc1_Fail Indicates that: VCC1 is below VCC1_FAIL threshold for typ. 2 µs in active mode VCC1 is below VCC1_FAIL threshold for more than 4 ms typ. during start up Bit [4] Vcc1_Uv_To: this bit is set in active mode if VCC1 is below the reset threshold for more than typ. 2 ms Bit [3] Vcc1_Ot: set if an overtemperature condition has been detected on VCC1 Bit [2] Vcc1_Sc: indicates a short circuit on VCC1. This bit is set if VCC1 stays below the VCC1_FAIL threshold 4 ms (typ.) after the power on reset or below the reset threshold 100 ms after the POR (Power On Reset) Bit [1] SDI_stuck@ Bit [0] WD_fail |
