DESCRIPTION
3124
info_length
R/W
IEEE 1394 bus-management field. Must be valid when bit 17 (linkEnable) in the host controller control
register at OHCI offset 50h/54h (see Section 4.16,
Host Controller Control Register
) is set to 1.
2316
crc_length
R/W
IEEE 1394 bus-management field. Must be valid when bit 17 (linkEnable) in the host controller control
register at OHCI offset 50h/54h (see Section 4.16,
Host Controller Control Register
) is set to 1.
150
rom_crc_value
R/W
IEEE 1394 bus-management field. Must be valid at any time bit 17 (linkEnable) in the host controller
control register at OHCI offset 50h/54h (see Section 4.16,
Host Controller Control Register
) is set to
1. The reset value is undefined if no serial EEPROM is present. If a serial EEPROM is present, then
this field is loaded from the serial EEPROM.
4.8
Bus Identification Register
The bus identification register externally maps to the first quadlet in the Bus_Info_Block and contains the constant
3133 3934h, which is the ASCII value of 1394.
