•
GEN_HOLD_COUNT0
: hold off interval setting for generator 1
•
GEN_HOLD_COUNT1
: hold off interval setting for generator 2
Allowed values are in the range from 0 (default value) to 1023 (maximum value). Avoid operation
with non-allowed values.
According to the time base selected in register
GEN_HOLD_BASE
[x] and the count set in
GEN_HOLD_COUNT
[x], the hold off interval may be calculated using the following formula:
HoldOff[x] [µs] = value(GEN_HOLD_BASE[x]) * value(GEN_HOLD_COUNT[x])
The hold off interval may range from 0 µs to 1,023,000 µs with variable absolute resolution.
Bit fields [15:10] of these registers are unused. When writing these bits, they must be set to zero.
14.2.50. Registers GEN_EDGE_SEL[0-1]
Each bit field [1:0] of these two registers holds the trigger edge selector for the relative pulse
generator.
•
GEN_EDGE_SEL0
: trigger edge selector for generator 1
•
GEN_EDGE_SEL1
: trigger edge selector for generator 2
Allowed values are in the range from 0 to 2 and are listed below. Avoid operation with non-listed
values.
•
When 0x0 the generator is triggered by a rising edge
•
When 0x1 the generator is triggered by a falling edge
•
When 0x2 the generator is triggered by both a rising and a falling edge
Bit fields [15:2] of these registers are unused. When writing these bits, they must be set to zero.
14.2.51. Register POLARITY_SEL0
Bit 0 of this register holds the polarity selector for trigger input TR.
Allowed values are in the range from 0 to 1 and are listed below. Avoid operation with non-listed
values.
•
When 0x0 polarity is normal (default value)
•
When 0x1 polarity is inverted
Bit field [15:1] of this register is unused. When writing these bits, they must be set to zero.
14.2.52. Register DRIVE_TIME0
The controller is capable of measuring the actual driving time for the light output LD.
This register contains the measured driving time, expressed as an unsigned sixteen bits integer, with
a resolution of 1 ms. Given a register value, the corresponding actual driving time for the light output
can be calculated as follows:
DrivingTime [ms] = value(DRIVING_TIME0) * 1.0
This register is updated as long as the output is activated. The register stop being updated when the
output turns off. Maximum measured value is 65535 ms, for longer driving times 65535 ms is always
returned. The value is computed in software, therefore it is approximate and subject to fluctuation.
This register is read only.
