Preliminary
2
b
Always set ”11b”.
16
reqCount
For OUTPUT_MORE and OUTPUT_LAST commands:
Set the data byte count to be stored from a host memory into the
IT- FIFO.
For OUTPUT_MORE_Immediate and OUTPUT_LAST_Immediate
commands:
Set ”0008h” which is the header’s byte count.
32
dataAddress
For OUTPUT_MORE and OUTPUT_LAST commands:
Set the start address of host memory where the data to be stored in
IT- FIFO.
For STORE_VALUE command :
Set the address of host memory where the data stored in the
storeDoublet field is in. (The upper 16- bit is specified with ”0”.)
28
branchAddress
Set the address of host memory to be processed next. This setting is valid only
when the Z field contains ”1” or greater value.
skipAddress
Set the address of host memory where the descriptor for bus reset process or
cycle lost case is stored.
For OUTPUT_LAST command, the skipAddress setting is valid only when the
reqCount field contains ”0” and it is the first descriptor.
4
Z
Set the number of descriptor to be processed next.
If no descriptor to be processed is outstanding, set ”0h” in this field.
If any descriptor is existing, set ”1h” to ”8h” as outstanding.
However, setting ”1h” must happen only when the next processed descriptor is
OUTPUT_LAST command and that descriptor has ”0” in the reqCount field.
16
xferStatus
This field indicates the transfer result (status) every packet transmitted,
following the ITContextControl register format. Valid only when s flag is set.
16
timeStamp
Set the timeout detection time to be stored in the xferStatus field. The time is
indicated in a value for (IsoCycleTimer.cycleCount value + Lower 3- bit of
cycleSeconds.)
16
storeDoublet
Set the 16- bit data to be stored in host memory. Actually zero data is padded in
the upper 16- bit, and the 32- bit data is stored in the memory.
32
quadlet
Store the packet header in this field.
