Special-Purpose Pins
(continued)
A11/MPI_IRQ
O
I/O
MPI
active-low interrupt request output.
After conguration, if the MPI is not used, this pin is a user-programmable I/O pin (see Note).
A10/MPI_BI
O
I/O
PowerPC mode MPI burst inhibit output.
After conguration, if the MPI is not used, this pin is a user-programmable I/O pin (see Note).
A9/MPI_ACK
O
I/O
In
PowerPC mode MPI operation, this is the active-high transfer acknowledge (TA) output. For
i960 MPI operation, it is the active-low ready/record (RDYRCV) output.
After conguration, if the MPI is not used, this pin is a user-programmable I/O pin (see Note).
A8/MPI_RW
I
I/O
In
PowerPC mode MPI operation, this is the active-low write/active-high read control signals.
For
i960 operation, it is the active-high write/active-low read control signal.
After conguration, if the MPI is not used, this pin is a user-programmable I/O pin (see Note).
A7/MPI_CLK
I
I/O
This is the clock used for the synchronous MPI interface. For
PowerPC, it is the CLKOUT
signal. For
i960, it is the system clock that is chosen for the i960 external bus interface.
After conguration, if the MPI is not used, this pin is a user-programmable I/O pin (see Note).
A[4:0]
I
I/O
For
PowerPC operation, these are the PowerPC address inputs. The address bit mapping (in
PowerPC/FPGA notation) is A[31]/A[0], A[30]/A[1], A[29]/A[2], A[28]/A[3], A[27]/A[4]. Note
that A[27]/A[4] is the MSB of the address. The A[4:2] inputs are not used in
i960 MPI mode.
After conguration, if the MPI is not used, this pin is a user-programmable I/O pin (see Note).
A[1:0]/
MPI_BE[1:0]
I
I/O
For
i960 operation, MPI_BE[1:0] provide the i960 byte enable signals, BE[1:0], that are used as
address bits A[1:0] in
i960 byte-wide operation.
After conguration, if the MPI is not used, this pin is a user-programmable I/O pin (see Note).
D[7:0]
I
I/O
During master parallel, peripheral, and slave parallel conguration modes, D[7:0] receive con-
guration data, and each pin has a pull-up enabled. During serial conguration modes, D0 is
the DIN input. D[7:0] are also the data pins for
PowerPC microprocessor mode and the
address/data pins for
i960 microprocessor mode.
After conguration, the pins are user-programmable I/O pins (see Note).
DIN
I
I/O
During slave serial or master serial conguration modes, DIN accepts serial conguration
data synchronous with CCLK. During parallel conguration modes, DIN is the D0 input. Dur-
ing conguration, a pull-up is enabled.
After conguration, this pin is a user-programmable I/O pin (see Note).
DOUT
O
I/O
During conguration, DOUT is the serial data output that can drive the DIN of daisy-chained
slave LCA devices. Data out on DOUT changes on the falling edge of CCLK.
After conguration, DOUT is a user-programmable I/O pin (see Note).

Description
Note: The FPGA States of Operation section contains more information on how to control these signals during start-up. The timing of DONE
release is controlled by one set of bit stream options, and the timing of the simultaneous release of all other conguration pins (and the
activation of all user I/Os) is controlled by a second set of options.
