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. Refer to Section 4.2.2.2 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 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 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 180.60, the line period would be 180.60 µs.
The line period can range from a minimum of 138.60 µs to a maximum of 100000.00 µs in
increments of 0.07.
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 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.
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.
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 value can range from a minimum of 2079 (0x00081F) to a maximum of 1500000
(0x16E360).
The integer value represents a multiplier and the actual line period is equal to the value in
this field times 2/30 µs. For example, if the value in this field is set to 3000 (0x000BB8),
then:
Line Period = 3000 x (2/30) µs
Line Period = 200 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 the line period.
