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
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 this 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 9.12, the exposure time will be 9.12 µs.
The exposure time can normally range from 4.56 µs to 19119997.00 µs in increments of
0.01. 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 bits) floating point num-
ber.
See Section
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 bits) floating point num-
ber.
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 bits) floating point num-
ber.
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 1 (0x00000001) to 4194301 (0x003FFFFD). 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 x 4.56 µs. For example, if the value in this field is set to 3 (0x00000003), then:
Exposure Time = 3 x 4.56 µs
Exposure Time = 13.68 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
for more information about exposure time.
