Preliminary

2

w

”11b” does not start to store packets until a packet specified in IRContextMatch.

sync field is received.

”00b” starts to store packets when incoming.

”01b” and ”10b” are unspecified codes.

In packet- per- buffer mode, only the ”w” field at the first descriptor of context

program is valid.

16

reqCount

Set the data byte count of host memory to store the packets.

32

dataAddress

Set the start address of host memory to store the packets.

28

branchAddress

Set the address of host memory where the next descriptor to be processed is

stored. This setting is valid only when the Z field contains ”1” or greater value.

4

Z

For buffer- fill mode :

Set ”1h” if there is the next descriptor to be processed.

Set ”0h” if there is no descriptor next.

For packet- per- buffer mode :

Set the number of descriptor to be processed next. Only ”Z” field in

INPUT_LAST command is valid.

Set ”0h” if there is no descriptor next.

Set ”1h” to ”8h” as the number if there is (are) descriptor(s).

16

xferStatus

This field indicates the transfer result (status) every packet stored in the

memory, following the IRContextControl register format. However, for

packet- per- buffer mode, the setting is valid only when s flag is set.

16

resCount

Set the byte count of the host memory where the packet is to be stored.

This field indicates the remaining byte count. However, for

packet- per- buffer mode, the setting is valid only when s flag is set.
