Fault Condition—Latched. A latched bit that is set when the channel enters a fault
condition. This bit is cleared when read, regardless of the current state of fault.
Lamp Strike Timeout—Latched. A latched bit that is set when the lamp fails to strike.
This bit is cleared when read.
Overvoltage—Latched. A latched bit that is set when a lamp overvoltage is present for
at least 64 lamp cycles. This bit is cleared when read.
Lamp Out—Latched. A latched bit that is set when a lamp out is detected. This bit is
cleared when read.
Lamp Overcurrent—Latched. A latched bit that is set when a lamp overcurrent is
detected. This bit is cleared when read.
Supply Voltage Monitor Low—Real Time. A real-time bit that reports the comparator
output of the SVML pin.
Supply Voltage Monitor High—Real Time. A real-time bit that reports the comparator
output of the SVMH pin.
Note 1: Writing to this register has no effect on it.
Note 2: See Figure 8 for more details on how the status bits are set.
Note 3: SR1 is cleared when only the following occurs:
? V CC drops below the UVLO threshold.
? The SVML or SVMH thresholds are crossed.
? The PDN hardware pin goes high.
? The PDNE software bit is written to a logic 1.
? The channel is disabled by the CH1D control bit.

FUNCTION
These five control bits determine the target value for the lamp current. 11111b is
35% of the nominal level and 00000b is 100% of the nominal level. These control
bits are used for fine adjustment of the lamp brightness.
