10.6.6 HcITLBufferPort register (R/W: 40H/C0H)
Table 61:
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 for read, C0H for write) once only, and then read or write all
the data bytes in 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 HcTransferCounter register; otherwise, an internal EOT signal is not generated to
set the bit 2 (AllEOTInterrupt) of the Hc PInterrupt register and update the
HcBufferStatus register.
