DFW-SX910/X710
Camera Command
Status Register
This camera complies with the IIDC 1394-based
Digital Camera Specification, version 1.30 (hereinafter
referred to as IIDC v1.30).
The standards document can be purchased from
1394TA (the 1394 Trade Association). Because it is
very helpful in understanding the explanations in this
Technical Manual, we recommend that you purchase a
copy of IIDC v1.30.
Memory Map
1394 devices have a 64-bit address space. The upper
10 bits show the bus ID (0~1023), and the next six bits
show the node ID (0~63). The IIDC standard requires
the next 20 bits to be 1.
The remaining 28 bits can be allocated to the camera
as addresses, but in reality, the first 4 bits are fixed at
0, so the largest number of bits that can be allocated to
the camera as address space is 24 bits.
The bus and node IDs may be changed if the topology
is restructured because of bus reset, so only the least
significant 32 address bits are shown in this Technical
Manual.
