Bit Field Value Description
31–0 ADDRESS_LSB/CONFIG_OFFSET 00000000h For packet types 2, 5, and 6:
to The 32-bit destination address or the 32 least significant bits of
FFFFFFFFh an extended destination address. This value is used in
conjunction with BYTE_COUNT to create a 64-bit aligned
RapidIO packet header address.
For packet type 8 (maintenance packet):
00000000h The right-aligned 24-bit register configuration offset. This value is
to used in conjunction with BYTE_COUNT to create a 64-bit aligned
00FFFFFFh RapidIO packet header Config_offset value. The 2 LSBs of this
field must be 0s because the smallest configuration access is 4
bytes.
