| 11:0 | TH_BUFFER_OFFSET | R/W | 0h | CPDMA THost Buffer Offset Value - The thost_buffer_offset will be written by the port into each frame SOP buffer descriptor buffer_offset field. The frame data will begin after the thost_buffer_offset value of bytes. A value of 0x0 indicates that there are no unused bytes at the beginning of the data and that valid data begins on the first byte of the buffer. A value of 0xF (decimal 15) indicates that the first 15 bytes of the buffer are to be ignored by the port and that valid buffer data starts on byte 16 of the buffer. This value is used for all channels. |
