Product Specification
R
after the DONE pin for that device goes High. (The exact
timing is determined by development system options.)
Since the DONE pin is open-drain and does not drive a High
value, tying the DONE pins of all devices together prevents
all devices in the chain from going High until the last device
in the chain has completed its configuration cycle. If the
DONE pin of a device is left unconnected, the device
becomes active as soon as that device has been config-
ured. Because only Spartan-XL, XC4000XLA/XV, and
XC5200 devices support Express mode, only these devices
can be used to form an Express mode daisy chain.
