HcTransferCounter Register
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
AllEOInterrupt, of the Hc
μ
PInterrupt register, and also update the HcBufferStatus
register.

Hc
μ
PInterrupt Register
All the bits in this register will be active on power-on reset. However, none of the
active bits will cause an interrupt on the interrupt pin (INT1) unless they are set by the
respective bits in the Hc
μ
PInterruptEnable register, and together with bit 0 of the
HcHardwareConfiguration register.
After this register (24H Read) is read, the bits that are active will not be reset, until
logic 1 is written to the bits in this register (A4H - Write) to clear it.
The bits in this register are cleared only when you write to this register indicating the
bits to be cleared. To clear all the enabled bits in this register, the HCD must write
FFH to this register.
