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 FT2232C
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 Chan-
nel A, a ‘1’ means that it has come from Channel B.
(iv) If the target device is unable to accept the data when it detects the start bit, it should stop the FSCLK until it can
accept the data.
