Line Period CSR
Note: The line period can be set by writing a floating point value to the Absolute Line Period field
or by writing an integer value to the Raw Line Period field. See Section 7.2.2.1 on page 164 for an
explanation of the difference between these two fields.
Register Base Address: 0x1600
Field Name: Register Status Offset: 0x0000 Size: 1 Byte Type: Read only
Description: The integer value in this field indicates the status of this control and status register:
0x00 = The register is not available
0x01 = The register is available and all related settings are OK
0x80 = A value in the register is set out of range
Field Name: Absolute Line Period Offset : 0x0001 Size: 4 Bytes Type : Read/Write
Description: Writing a floating point value to this field sets the line period in µs. For example, if the value in this
field is set to 180.6, the line period will be 180.6 µs.
The allowed range for the absolute line period can vary depending on the camera model and how
the camera is configured. You should check the absolute min and absolute max fields of this
register to determine the allowed range with the current configuration. The increment is 0.1.
The value in this field is a standard IEEE-754 single precision (32 bit) floating point number.
See Section 4.2 on page 71 for more information about the line period.
Field Name: Absolute Min Offset : 0x0005 Size: 4 Bytes Type : Read only
Description: Minimum allowed floating point value for the absolute line period setting. This field is updated to
reflect limitations caused by the way that any related features are set.
The value in this field is a standard IEEE-754 single precision (32 bit) floating point number.
Field Name: Absolute Max Offset : 0x0009 Size: 4 Bytes Type : Read only
Description: Maximum allowed floating point value for the absolute line period setting. This field is updated to
reflect limitations caused by the way that any related features are set.
The value in this field is a standard IEEE-754 single precision (32 bit) floating point number.
Field Name: Raw Line Period Offset : 0x000D Size: 4 Bytes Type : Read/Write
Description: Writing an integer value to this field sets the line period.
The allowed range for this value can vary depending on the camera model and how the camera is
configured. You should check the raw min and raw max fields of this register to determine the
allowed range with the current configuration.
The integer value represents a multiplier, and the line period is equal to the value in this field times
0.1 µs. For example, if the value in this field is set to 1500, then:
Line Period = 1500 x 0.1 µs
Exposure Time = 150 µs
The bytes in this field are interpreted as follows:
Byte 1 = Low byte of the raw value
Byte 2 = Mid byte of the raw value
Byte 3 = High byte of the raw value
Byte 4 = Always 0 (not used)
