32 * JTAG adapters based on the FT2232 full and high speed USB parts are
33 * popular low cost JTAG debug solutions. Many FT2232 based JTAG adapters
34 * are discrete, but development boards may integrate them as alternatives
35 * to more capable (and expensive) third party JTAG pods. Since JTAG uses
36 * only one of the two ports on these devices, on integrated boards the
37 * second port often serves as a USB-to-serial adapter for the target's
38 * console UART even when the JTAG port is not in use. (Systems which
39 * support ARM's SWD in addition to JTAG, or instead of it, may use that
40 * second port for reading SWV trace data.)
42 * FT2232 based JTAG adapters are "dumb" not "smart", because most JTAG
43 * request/response interactions involve round trips over the USB link.
44 * A "smart" JTAG adapter has intelligence close to the scan chain, so it
45 * can for example poll quickly for a status change (usually taking on the
46 * order of microseconds not milliseconds) before beginning a queued
47 * transaction which require the previous one to have completed.
49 * There are dozens of adapters of this type, differing in details which
50 * this driver needs to understand. Those "layout" details are required
51 * as part of FT2232 driver configuration.
53 * This code uses information contained in the MPSSE specification which was
55 * http://www.ftdichip.com/Documents/AppNotes/AN2232C-01_MPSSE_Cmnd.pdf
56 * Hereafter this is called the "MPSSE Spec".
58 * The datasheet for the ftdichip.com's FT2232D part is here:
59 * http://www.ftdichip.com/Documents/DataSheets/DS_FT2232D.pdf
61 * Also note the issue with code 0x4b (clock data to TMS) noted in
62 * http://developer.intra2net.com/mailarchive/html/libftdi/2009/msg00292.html
63 * which can affect longer JTAG state paths.
