LTDVE4CH-20 | INSTRUCTIONS MANUAL
Allowed values are in the range from 1 (default value) to 1023 (maximum value) and are expressed
in ms, so the maximum turn-on time can range from 1 ms to 1023 ms with a resolution of 1 ms. Avoid
operation with non-allowed values.
Bit fields [15:10] of these registers are unused. When writing these bits, they must be set to zero.
14.2.16. Registers PRT_ENA_ON[0:3]
Bit 0 of these registers holds the enable flag for the limitation of turn-on time for light outputs LD1,
LD2, LD3 and LD4.
PRT_ENA_ON0
: enable flag for the limitation of turn-on time for light output LD1
PRT_ENA_ON1
: enable flag for the limitation of turn-on time for light output LD2
PRT_ENA_ON2
: enable flag for the limitation of turn-on time for light output LD3
PRT_ENA_ON3
: enable flag for the limitation of turn-on time for light output LD4
When set to zero the limitation of turn-on time is disabled (default value), when set to one the
limitation of turn-on time is enabled.
Bit fields [15:1] of these registers are unused. When writing these bits, they must be set to
zero.
14.2.17. Registers PRT_CNT_OFF[0:3]
Each bit field [9:0] of these registers holds the minimum turn-off time for light outputs LD1, LD2, LD3
and LD4.
PRT_CNT_OFF0
: minimum turn-off time for light output LD1
PRT_CNT_OFF1
: minimum turn-off time for light output LD2
PRT_CNT_OFF2
: minimum turn-off time for light output LD3
PRT_CNT_OFF3
: minimum turn-off time for light output LD4
Allowed values are in the range from 1 (default value) to 1023 (maximum value) and are expressed
in ms, so the minimum turn-off time can range from 1 ms to 1023 ms with a resolution of 1 ms. Avoid
operation with non-allowed values.
Bit fields [15:10] of these registers are unused. When writing these bits, they must be set to zero.
14.2.18. Registers PRT_ENA_OFF[0:3]
Bit 0 of these registers holds the enable flag for the limitation of turn-off time for light outputs LD1,
LD2, LD3 and LD4.
PRT_ENA_OFF0
: enable flag for the limitation of turn-off time for light output LD1
PRT_ENA_OFF1
: enable flag for the limitation of turn-off time for light output LD2
PRT_ENA_OFF2
: enable flag for the limitation of turn-off time for light output LD3
PRT_ENA_OFF3
: enable flag for the limitation of turn-off time for light output LD4
When set to zero the limitation of turn-off time is disabled (default value), when set to one the
limitation of turn-off time is enabled.
Bit fields [15:1] of these registers are unused. When writing these bits, they must be set to zero.
14.2.19. Registers CUR_RANGE[0:3]
Each bit field [1:0] of these four registers selects the current range for the relevant light output.
CUR_RANGE0
: current range setting for light output LD1
