HcTransferCounter register (R/W: 22H/A2H)
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 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
μ
PInterrupt register, and also update the HcBufferStatus
register.
