Description
Special-Purpose Pins (continued)
WR/MPI_RW
I
WR is used in asynchronous peripheral mode. A low on WR transfers data on D[7:0] to the
FPGA.
In MPI mode, a high on MPI_RW allows a read from the data bus, while a low causes a write
transfer to the FPGA.
I/O After conguration, if the MPI is not used, WR/MPI_RW is a user-programmable I/O pin.*
PPC_A[14:31]
I
During MPI mode the PPC_A[14:31] are used as the address bus driven by the PowerPC
bus master utilizing the least-signicant bits of the PowerPC 32-bit address.
MPI_BURST
IMPI_BURST is driven low to indicate a burst transfer is in progress in MPI mode. Driven high
indicates that the current transfer is not a burst.
MPI_BDIP
IMPI_BDIP is driven by the PowerPC processor in MPI mode. Assertion of this pin indicates
that the second beat in front of the current one is requested by the master. Negated before
the burst transfer ends to abort the burst data phase.
MPI_TSZ[0:1]
I
MPI_TSZ[0:1] signals are
driven by the bus master in MPI mode to indicate the data transfer
size for the transaction. Set 01 for byte, 10 for half-word, and 00 for word.
A[21:0]
O
During master parallel mode A[21:0] address the conguration EPROMs up to 4M bytes.
I/O If not used for MPI these pins are user-programmable I/O pins after conguration.*
MPI_ACK
O
In MPI mode this is driven low indicating the MPI received the data on the write cycle or
returned data on a read cycle.
I/O If not used for MPI these pins are user-programmable I/O pins after conguration.*
MPI_CLK
I
This is the PowerPC synchronous, positive-edge bus clock used for the MPI interface. It can
be a source of the clock for the embedded system bus. If MPI is used this will be the AMBA
bus clock.
I/O If not used for MPI these pins are user-programmable I/O pins after conguration.*
MPI_TEA
OA low on the MPI transfer error acknowledge indicates that the MPI detects a bus error on
the internal system bus for the current transaction.
I/O If not used for MPI these pins are user-programmable I/O pins after conguration.*
MPI_RTRY
O
This pin requests the MPC860 to relinquish the bus and retry the cycle.
I/O If not used for MPI these pins are user-programmable I/O pins after conguration.*
D[0:31]
I/O Selectable data bus width from 8, 16, 32-bit in MPI mode. Driven by the bus master in a write
transaction and driven by MPI in a read transaction.
I
D[7:0] receive conguration data during master parallel, peripheral, and slave parallel cong-
uration modes when WR is low and each pin has a pull-up enabled. During serial congura-
tion modes, D0 is the DIN input.
O
D[7:3] output internal status for asynchronous peripheral mode when RD is low.
I/O After conguration, if MPI is not used, the pins are user-programmable I/O pins.*
DP[0:3]
I/O Selectable parity bus width in MPI mode from 1, 2, 4-bit, DP[0] for D[0:7], DP[1] for D[8:15],
DP[2] for D[16:23], and DP[3] for D[24:31].
After conguration, if MPI is not used, the pins are user-programmable I/O pin.*
* 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.
