10.6.4 HcReadBackITL0Length register (R: 2DH)
10.6.5 HcReadBackITL1Length register (R: 2EH)
Table 57:
This register’s value stands for the current number of data bytes inside an ITL0 buffer
to be read back by the microprocessor. The HCD must set the HcTransferCounter
equivalent to this value before reading back the ITL0 buffer RAM.
Code (Hex): 2D — read
Table 59:
