LOADED SID DESCRIPTION
Output leakage detection (OLD) data bit for OUT8 to OUT15. The 8-bit data bit assignment of the output
channel is:
Bits[139:132]
Bit 132 = OUT8 OLD
Bit 133 = OUT9 OLD
…
Bit 138 = OUT14 OLD
Bit 139 = OUT15 OLD
0 = Normal operation (default)
1 = Output current leaks to GND when the output is off
Bits[143:140]
Reserved data. These four bits of data are not set and can be either '0' or '1'.
LED short detection (LSD) data bit for OUT0 to OUT7. The 8-bit data bit assignment of the output channel is:
Bits[151:144]
Bit 144 = OUT0 LSD
Bit 145 = OUT1 LSD
…
Bit 150 = OUT6 LSD
Bit 151 = OUT7 LSD
0 = Normal operation (default)
1 = LED is shorted
Bits[155:152]
Reserved data. These four bits of data are not set and can be either '0' or '1'.
LED short detection (LSD) data bit for OUT8 to OUT15. The 8-bit data bit assignment of the output channel is:
Bits[163:156]
Bit 156 = OUT8 LSD
Bit 157 = OUT9 LSD
…
Bit 162 = OUT14 LSD
Bit 163 = OUT15 LSD
0 = Normal operation (default)
1 = LED is shorted
Bits[167:164]
Reserved data. These four bits of data are not set and can be either '0' or '1'.
LED open detection (LOD) data bit for OUT0 to OUT7. The 8-bit data bit assignment of the output channel is:
Bits[175:168]
Bit 168 = OUT0 LOD
Bit 169 = OUT1 LOD
…
Bit 174 = OUT6 LOD
Bit 175 = OUT7 LOD
0 = Normal operation (default)
1 = LED is open or connected to GND with low resistance
Bits[179:176]
Reserved data. These four bits of data are not set and can be either '0' or '1'.
LED open detection (LOD) data bit for OUT8 to OUT15. The 8-bit data bit assignment of the output channel is:
Bits[187:180]
Bit 180 = OUT8 LOD
Bit 181 = OUT9 LOD
…
Bit 186 = OUT14 LOD
Bit 187 = OUT15 LOD
0 = Normal operation (default)
1 = LED is open or connected to GND with low resistance
Bits[191:188]
Reserved data. These four bits of data are not set and can be either '0' or '1'.
