ORCA Series 2 FPGAs
FPGA Configuration Modes
(continued)
Asynchronous Peripheral Mode
Figure 42 shows the connections needed for the asyn-
chronous peripheral mode. In this mode, the FPGA
system interface is similar to that of a microprocessor-
peripheral interface. The microprocessor generates the
control signals to write an 8-bit byte into the FPGA. The
FPGA control inputs include active-low
CS0
and active-
high CS1 chip selects, a write
WR
input, and a read
RD
input. The chip selects can be cycled or maintained at
a static level during the configuration cycle. Each byte
of data is written into the FPGA’s D[7:0] input pins.
The FPGA provides a RDY status output to indicate
that another byte can be loaded. A low on RDY indi-
cates that the double-buffered hold/shift registers are
not ready to receive data, and this pin must be moni-
tored to go high before another byte of data can be
written. The shortest time RDY is low occurs when a
byte is loaded into the hold register and the shift regis-
ter is empty, in which case the byte is immediately
transferred to the shift register. The longest time for
RDY to remain low occurs when a byte is loaded into
the holding register and the shift register has just
started shifting configuration data into configuration
RAM.
The RDY status is also available on the D7 pin by
enabling the chip selects, setting
WR
high, and apply-
ing
RD
low, where the
RD
input is an output enable for
the D7 pin when
RD
is low. The D[6:0] pins are not
enabled to drive when
RD
is low and, thus, only act as
input pins in asynchronous peripheral mode.

Schematic
Synchronous Peripheral Mode
In the synchronous peripheral mode, byte-wide data is
input into D[7:0] on the rising edge of the CCLK input.
The first data byte is clocked in on the second CCLK
after
INIT
goes high. Subsequent data bytes are
clocked in on every eighth rising edge of CCLK. The
RDY signal is an output which acts as an acknowledge.
RDY goes high one CCLK after data is clocked and,
after one CCLK cycle, returns low. The process repeats
until all of the data is loaded into the FPGA. The data
begins shifting on DOUT 1.5 cycles after it is loaded in
parallel. It requires additional CCLKs after the last byte
is loaded to complete the shifting. Figure 43 shows the
connections for synchronous peripheral mode.
As with master modes, the peripheral modes can be
used as the lead FPGA for a daisy chain of slave
FPGAs.
