Register Name:
Register Description:
Register Address:
Bit #
Name
Default
Bits 7 to 0: Driver Fault Monitor Interrupt Enable Channel n (DFMIEn). When this bit is set, a change in DFM
status can generate an interrupt in monitor n.
Register Name:
Register Description:
Register Address:
Bit #
Name
Default
Bits 7 to 0: Loss-of-Signal Interrupt Status Channel n (LOSISn). When this bit is set, it indicates an LOS status
has transitioned from a 0 to 1 or 1 to 0 and was detected for LIUn. The interrupt for LIUn is enabled in LOSIS. This
bit when latched is cleared by a read operation to the register if GISC.CWE is reset. This bit, when latched, is
cleared by a write operation to the bit if GISC.CWE is set.

Bits 7 to 0: Driver Fault Status Register Channel n (DFMISn). When this bit is set, it indicates a DFM status has
transitioned from 0 to 1 or 1 to 0 and was detected for LIUn. The interrupt for LIUn is enabled by in DFMIE. This bit
when latched is cleared by a read operation to the register if GISC.CWE is reset. This bit, when latched, is cleared
by a write operation to the bit if GISC.CWE is set.

Default
Bits 7 to 0: Software Reset (SWR). Whenever any write is performed to this register, at least a 1μs reset will be
generated that resets the DS26303. All the registers will be restored to their default values. A read operation will
always read back all zeros.
