Figure 9–8. AS Multi-Device Configuration When Both Devices in the Chain Receive Different Sets of Configuration Data
Notes to
(1) Connect the pull-up resistors to V
(2) Connect the repeater buffers between the Stratix V master and slave device for AS_DATA1/DATA0 and DCLK.
(3) You can leave the nCEO pin unconnected or use it as a user I/O pin when it does not feed another device's nCE pin.
(4) For the appropriate MSEL settings based on POR delay settings, set the slave device MSEL setting to the PS scheme. Refer to
(5) The MSEL pin settings vary for different configuration voltage standards and POR delays. To connect MSEL, refer to
(6) You can use the CLKUSR pin to supply the external clock source to drive the DCLK during configuration. The maximum frequency specification

In the AS multi-device configuration, the nSTATUS, nCONFIG, and CONF_DONE pins
are tied together. Therefore, all devices initialize and enter user mode at the same
time. If any device detects an error, configuration stops for the entire chain and you
must reconfigure all devices. For example, if the first device flags an error on
nSTATUS, it resets the chain by pulling its nSTATUS pin low. This behavior is similar
to a single device detecting an error.
In this configuration scheme, the first Stratix V device in the chain is the configuration
master and controls the configuration of the entire chain. You must connect its MSEL
pins to select the AS configuration scheme. The remaining Stratix V devices are
configuration slaves. You must connect their MSEL pins to select the PS configuration
scheme. Any other Altera
the chain as the configuration slave.
