Preliminary
and dataAddress field contains ”10000000h” which is the start address of host memory where the packet is
stored for descriptor- 1 and ”20000000h” for descriptor- 2. Also, the branchAddress field for descriptor- 2 con-
tains ”90000000h” which is the start address of host memory where the context program- 2 to control the host
memory for storing the next packet is stored and the Z field contains ”2h” which is a number of descriptor in
context program- 2.
The ” i ” field of the INPUT_LAST command is being set to ”11b” so that an interrupt event is reported after
completion of isochronous packet receive process.
