Configuration Modes
(continued)
Daisy Chain
The
ORCA
Foundry for ATT3000 Development System
is used to create a composite configuration bit stream
for selected FPGAs including a preamble, a length
count for the total bit stream, multiple concatenated
data programs, a postamble, plus an additional fill bit
per device in the serial chain. After loading and passing
on the preamble and length count to a possible daisy
chain, a lead device will load its configuration data
frames while providing a high DOUT to possible down-
stream devices as shown in Figure 25. Loading contin-
ues while the lead device has received its configuration
program and the current length count has not reached
the full value. Additional data is passed through the
lead device and appears on the data out (DOUT) pin in
serial form. The lead device also generates the CCLK
to synchronize the serial output data and data in of
downstream FPGAs. Data is read in on DIN of slave
devices by the positive edge of CCLK and shifted out
the DOUT on the negative edge of CCLK. A parallel
master mode device uses its internal timing generator
to produce an internal CCLK of eight times its EPROM
address rate, while a peripheral mode device produces
a burst of eight CCLKs for each chip select and write-
strobe cycle. The internal timing generator continues to
operate for general timing and synchronization of
inputs in all modes.
