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 + 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)
ATL buffer length has been set to be 800H, then the maximum ITL buffer length can
only be set as 400H.
