Data inputs.
In AS or PS configuration schemes, they function as user I/O
pins during configuration, which means they are tri-stated.
After FPP configuration, DATA[7..2] are available as user
I/O pins and the state of these pin depends on the
Dual-Purpose Pin settings.
The byte-wide or word-wide configuration data is presented
to the target Cyclone III device on
DATA[15..0] , respectively, in the AP configuration
scheme (for Cyclone III devices only). After AP configuration,
DATA[7..2] are dedicated bidirectional pins with optional
user control.
Data inputs. Word-wide configuration data is presented to the
target Cyclone III device on DATA[15..0].
In PS, FPP, or AS configuration schemes, they function as
user I/O pins during configuration, which means they are
tri-stated.
After AP configuration, DATA[15:8] are dedicated
bidirectional pins with optional user control.
24-bit address bus from the Cyclone III device to the parallel
flash in AP mode. Connects to the A[24:1] bus on the
Numonyx P30 or P33 flash.
Active-low reset output. Driving the nRESET pin low resets
the parallel flash. Connects to the RST# pin on the Numonyx
P30 or P33 flash.
Active-low address valid output. Driving the nAVD pin low
during a read or write operation indicates to the parallel flash
that valid address is present on the PADD[23..0] address
bus. Connects to the ADV# pin on the Numonyx P30 or P33
flash.
Active-low output enable to the parallel flash. Driving the
nOE pin low during a read operation enables the parallel flash
outputs (DATA[15..0]). Connects to the OE# pin on the
Numonyx P30 or P33 flash.
Active-low write enable to the parallel flash. Driving the nWE
pin low during a write operation indicates to the parallel flash
that data on the DATA[15..0] bus is valid. Connects to
the WE# pin on the Numonyx P30 or P33 flash.
