10.6.1 HcITLBufferLength register (R/W: 2AH/AAH)
10.6.2 HcATLBufferLength register (R/W: 2BH/ABH)
10.6 HC buffer RAM control registers
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
where: ITL buffer size
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)
ATL buffer length has been set to be 800H, then the maximum ITL buffer length can
only be set as 400H.
