Write to this register to assign the ITL buffer size in bytes: ITL0 and ITL1 are assigned the
same value. For example, if HcITLBufferLength register is set to 2 kbytes, then ITL0 and
ITL1 would be allocated 2 kbytes each.
Must follow the formula:
ATL buffer length + 2
where: ITL buffer size = ITL0 buffer length = ITL1 buffer length
Code (Hex): 2A — read
Code (Hex): AA — write
Table 53.
Write to this register to assign ATL buffer size.
Code (Hex): 2B — read
Code (Hex): AB — write
Remark: The maximum total RAM size is 1000H (4096 in decimal) bytes. That means
ITL0 (length) + ITL1 (length) + ATL (length)
length has been set to be 800H, then the maximum ITL buffer length can only be set as
400H.
