Default read mode of the supported parallel flash memory and all writes to the
parallel flash memory are asynchronous. Both the parallel flash families support a
synchronous read mode, with data supplied on the positive edge of DCLK.
The serial clock (DCLK) generated by Cyclone IV E devices controls the entire
configuration cycle and provides timing for the parallel interface.
Multi-Device AP Configuration
You can configure multiple Cyclone IV E devices using a single parallel flash. You can
cascade multiple Cyclone IV E devices using the chip-enable (nCE) and
chip-enable-out (nCEO) pins. The first device in the chain must have its nCE pin
connected to GND. You must connect its nCEO pin to the nCE pin of the next device in
the chain. Use an external 10-k pull-up resistor to pull the nCEO signal high to its
V
its configuration data from the bitstream, it drives the nCEO pin low, enabling the next
device in the chain. You can leave the nCEO pin of the last device unconnected or use
it as a user I/O pin after configuration if the last device in the chain is a Cyclone IV E
device. The nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA[15..8], and
DATA[7..0] pins of each device in the chain are connected

configuration of the entire chain. You must connect its MSEL pins to select the AP
configuration scheme. The remaining Cyclone IV E devices are used as configuration
slaves. You must connect their MSEL pins to select the FPP configuration scheme. Any
other Altera device that supports FPP configuration can also be part of the chain as a
configuration slave.
The following are the configurations for the DATA[15..0] bus in a multi-device AP
