Camera Command Status Register

This camera complies with 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 standards require the next 20 bits to be 1.

---BusID---

bbbbbbbb bbnnnnnn 11111111 11111111 11110000 11110000 00000000 00000000

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 User’s Guide.
