Outgoing Fast Serial Data
To send fast serial data out of the chip, the external device must clock. If the chip has
data ready to send, it will drive FSDO low to indicate the start bit. It will not do this if it
is currently receiving data from the external device.
Figure 34 - Fast Opto-Isolated Serial Data Format - Data output from the FT2232D
Notes:
(i) Start Bit is always 0.
(ii) Data is sent LSB first.
(iii) The source bit (SRCE) indicates which channel the data has come from. A ‘0’ means
that it has come from Channel A, a ‘1’ means that it has come from Channel B.
