10.6.6 HcITLBufferPort register (R/W: 40H/C0H)
10.6.7 HcATLBufferPort register (R/W: 41H/C1H)
This is the ITL buffer RAM read/write port. The bits 15 to 8 contain the data byte that
comes from the ITL buffer RAM’s even address. The bits 7 to 0 contain the data byte
that comes from the ITL buffer RAM’s odd address.
Code (Hex): 40 — read
Code (Hex): C0 — write
Table 63:
The HCD must set the byte count into the HcTransferCounter register and check the
HcBufferStatus register before reading from or writing to the buffer. The HCD must
write the command (40H to read, C0H to write) once only, and then read or write both
bytes of the data word. After every read/write, the pointer of ITL buffer RAM will be
automatically increased by two to point to the next data word until it reaches the value
of the HcTransferCounter register; otherwise, an internal EOT signal is not generated
to set bit 2 (AllEOTInterrupt) of the Hc PInterrupt register and update the
HcBufferStatus register.
The HCD must take care of the fact that the internal buffer RAM is organized in bytes.
The HCD must write the byte count into the HcTransferCounter register, but the HCD
reads or writes the buffer RAM by 16 bits (by 1 data word).
This is the ATL buffer RAM read/write port. Bits 15 to 8 contain the data byte that
comes from the Acknowledged Transfer List (ATL) buffer RAM’s odd address.
Bits 7 to 0 contain the data byte that comes from the ATL buffer RAM’s even address.
