10.4.3 HcTransferCounter register (R/W: 22H/A2H)
Table 39:
This register holds the number of bytes of a PIO or DMA transfer. For a PIO transfer,
the number of bytes being read or written to the Isochronous Transfer List (ITL) or
Acknowledged Transfer List (ATL) buffer RAM must be written into this register. For a
DMA transfer, the number of bytes must be written into this register as well. However,
for this counter to be read into the DMA counter, the HCD must set bit 2
(DMACounterSelect) of the HcDMAConfiguration register. The counter value for ATL
must not be greater than 1000H, and for ITL it must not be greater than 800H. When
the byte count of the data transfer reaches this value, the HC will generate an internal
EOT signal to set bit 2 (AllEOTInterrupt) of the Hc PInterrupt register, and also
update the HcBufferStatus register.
Code (Hex): 22 — read
Code (Hex): A2 — write
