Table 14. SID Load Description (continued)

COMMON SHIFT

LOADED SID DESCRIPTION

Output leakage detection (OLD) data bit for OUT8 to OUT15. The 8-bit data bit assignment of the output

channel is:

Bit 132 = OUT8 OLD

Bit 133 = OUT9 OLD

Bits[139:132]

…

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:

Bit 144 = OUT0 LSD

Bit 145 = OUT1 LSD

…

Bits[151:144]

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:

Bit 156 = OUT8 LSD

Bit 157 = OUT9 LSD

…

Bits[163:156]

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:

Bit 168 = OUT0 LOD

Bit 169 = OUT1 LOD

…

Bits[175:168]

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:

Bit 180 = OUT8 LOD

Bit 181 = OUT9 LOD

…

Bits[187:180]

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'.
