Can XPLA2 devices be daisy-chained for configuration?
Yes, the configuration mode of the lead device can be set to any of the supported configuration modes, all of the other devices in the chain must be set in slave serial mode. CCLK, DONE, PRGMN, and RESETN are all connected in parallel. The devices are daisy-chained by connecting DOUT to DIN through the chain.
For more details on configuration, see the data sheet for these devices.
