Table 65:
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 (41H to read, C1H to write) once only, and then read or write both
bytes of the data word. After every read/write, the pointer of ATL 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 the bit 2 (AllEOTInterrupt) of the Hc PInterrupt register and update the
HcBufferStatus register.
The HCD must take care of the difference: the internal buffer RAM is organized in
bytes, so 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).
