Status Register [R1, R0] = [0,0]
Register Functionality
The devices have four 8-bit-wide registers for configuration and monitoring (Table 1).

X = Unknown. These bits are dependent on the DI logic and C/Q inputs.
The Status register reflects the logic levels of C/Q and DI and shows the source of interrupts that cause an IRQ hardware inter-
rupt. The IRQ interrupt is asserted when an alarm condition (OTemp, UV33Int, UV24, C/QFault, DoFault, WuInt) is detected. All
bits in the Status register are read-only. The interrupt bits return to the default state after the Status register is read. If a C/Q or
DO fault condition persists, the associated interrupt bits are immediately set after the Status register is read.
BIT
NAME
DESCRIPTION
D7
Wulnt
Wake-Up Interrupt Request. WuInt is set when an IO-Link wake-up request pulse is
detected on C/Q and the WuIntEn bit in the Mode register is set. IRQ asserts when
WuInt is set to 1. Read the Status register to clear the WuInt bit and deassert IRQ.
D6
DoFaultInt
DO Fault Interrupt. DoFaultInt interrupt bit and DoFault bit (in the Mode register) are
set when a fault condition occurs on the DO driver output. The device registers a fault
condition when a short circuit or voltage fault is detected on DO (see the DO Fault
Detection section for more information). IRQ asserts when DoFaultInt is 1. Read the
Status register to clear the DoFaultInt bit and deassert IRQ.
D5
DiLvl
DI Logic Level. The DiLvl bit mirrors the current logic level at the DI input. It is the
inverse of the LI output and is always active regardless of the state of the LiDis bit (Table
2). DiLvl does not affect IRQ. DiLvl is not changed when the Status register is read.
