Set the quadlet count of the bus_info_block included in
the 1394 configuration ROM.
00h
Set the 1394 configuration ROM byte count in quadlet unit.
0000h
Set the 1394 configuration ROM CRC.
3.2.6. Bus Identification
This register stores and indicates the first data of the bus_Info_block field in the 1934 configuration ROM (off-
set “FFFF_F000_0404h”).

These bits indicate ”3133_3934h” which means the
”1394”d in ASCII code.
3.2.7. Bus Options
This register stores and indicates the second data of the bus_Info_block field in the 1934 configuration ROM
(off- set “FFFF_F000_0404h”). The max_rec field is available only when the HCControl.linkEnable bit is set.
If a packet, which has the transmission speed over the setting, is received, it is invalid.

------------------------------------------
These bits are used to specify the maximum byte count that
is possible for payloading at the block- write- request
packet receipt. *: ”512” is indicated at the hardware
reset state. For the software reset state, the current stored
data are indicated.
010b
Specify the link transfer rate.
As the maximum transfer rate is S400, Link_spd shows
”010b.”
