This slide illustrates the buffer of bytes that would need to be constructed to clock out (write) two bytes of data with the values AA and 55 on the falling edge of a clock with the most significant bit (MSB) first. The opcode is 11, the length is 2 (defined as a low byte of 01 and a high byte of 00) followed by the actual data AA 55. This results in an FT_Write call sending five bytes in total.
