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 for read, C1H for 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 HcTransferCounter register; otherwise, an internal EOT signal is not
generated to set the bit 2 (AllEOTInterrupt) of the HcµPInterrupt 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).
