Boundary-Scan Mode
In the boundary-scan mode, configuration is done through
the IEEE 1149.1 Test Access Port. Note that the
PROGRAM pin must be pulled High prior to reconfiguration.
A Low on the PROGRAM pin resets the TAP controller and
no JTAG operations can be performed.

When all DONE pins
are released, DONE goes High
and start-up sequences complete.
If no errors,
later FPGAs enter start-up phase
releasing DONE.
If no errors,
first FPGAs enter start-up phase
releasing DONE.
Once per bitstream,
FPGA checks data using CRC
and pulls INIT Low on error.
FPGA makes a final
clearing pass and releases
INIT when finished.
FPGA starts to clear
configuration memory.
