of a processing element through regular read and write operations rather than maintenance operations. The double-word
offset is right-justified in the register. As is the case with all registers, an external processor writing to LCSBA1CSR should
not assume it has been written until a response has been received.

The above register is described in the RIO Specification Part 1, sec. 5.5.3
Base Device ID CSR
The sRIO searchable source and destination IDs are contained in the Base Device ID CSR, and are programmed by
sRIO according to the sRIO specification. There are locations for both 8 and 16 bit device IDs as described in the RapidIO,
Part 3, Common Transport Specification in section 3.5.1. The SerB shall allow programming of both, in order to allow both
8 and 16 bit operations simultaneously. Both device IDs may be read by any of the interfaces with access to the configura-
tion registers.
The device IDs are cleared only by Master Reset or by a specific write to the Base Device ID CSR. Other resets, such
as Load Configuration will have no affect on the Base Device ID CSR. The Base Device ID CSR has no shadow register.
Note: This register is in the sRIO spec and that spec overrides this info.

LRG_BASE_DEVID 0xFFFF
Large Base Device ID:
SerB Source/Destination ID is 16 bits. The Base ID of the device in a
large common transport system. This field is valid only if bit 27 of the
Processing Element Features CAR is set.
30:17 BASE_DEVID
0xFF
Base Device ID:
SerB Source/Destination ID is 8 bits. The Base ID of the device in a
small common transport system (RIO device ID)

Host Base Device ID Lock CSR
The host base device ID lock CSR contains the base device ID value for the processing element in the system that is
responsible for initializing this processing element. The HBDID field is a write-once/resettable field which provides a lock
function. Once the HBDID field is written, all subsequent writes to the field are ignored, except in the case that the value
written matches the value contained in the field. In this case, the register is re-initialized to 0xFFFF. After writing the HBDID
field, a processing element must then read the host base device ID lock CSR to verify that it owns the lock before
attempting to initialize this processing element.
