Exposure Time CSR
Note: The exposure time can be set by writing a floating point value to the Absolute Exposure
Time field or by writing an integer value to the Raw Exposure Time field. Refer to Section 4.2.2.2
for an explanation of the difference between these two fields.
Register Base Address: 0x1500
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 register:
0x00 = The register is not available
0x01 = The register is available. All related settings are OK
0x80 = A value in the register is set out of range
Field Name: Absolute Exposure Time Offset: 0x0001 Size: 4 Bytes Type: Read / Write
Description: Writing a floating point value to this field sets the exposure time in µs. For example, if the
value in this field is set to 12.25, the exposure time will be 12.25 µs.
The exposure time can normally range from 10.0 µs to 100000.00 µs in increments of 0.07.
The actual available range may be limited by the way any related parameters are set.
The value in this field is a standard IEEE-754 single precision (32 bit) floating point number.
See Section 3.3 for more information about exposure time.
Field Name: Absolute Min Offset: 0x0005 Size: 4 Bytes Type: Read only
Description: Minimum allowed floating point value for the absolute exposure time setting. This field is
updated to reflect limitations caused by the way 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 exposure time setting. This field is
updated to reflect any limitations caused by the way 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 Exposure Time Offset: 0x000D Size: 4 Bytes Type: Read / Write
Description: Writing an integer value to this field sets the exposure time.
The value can normally range from 150 (0x000096) to 1500000 (0x16E360). The actual
available range may be limited by the way any related parameters are set.
The integer value represents a multiplier and the actual exposure time is equal to the value
in this field times 2/30 µs. For example, if the value in this field is set to 1200 (0x0004B0),
then:
Exposure Time = 1200 x (2/30) µs
Exposure Time = 80 µs
The 4 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 0x00 (not used)
See Section 3.3 for more information about exposure time.
