Code (Hex): 2D — read
10.6.5
HcReadBackITL1Length register (2EH—Read only)
This register’s value stands for the current number of data bytes inside the ITL1 buffer
to be read back by the microprocessor. The HCD must set the HcTransferCounter
equivalent to this value before reading back the ITL1 buffer RAM.
Code (Hex): 2E — read
10.6.6
HcITLBufferPort register (40H—Read, C0H—Write)
This is the ITL buffer RAM read/write port. The bits 15:8 contain the data byte that
comes from the ITL buffer RAM’s even address. The bits 7:0 contain the data byte
that comes from the ITL buffer RAM’s odd address.
