Abstract:
A method of configuring programmable devices comprising: providing a source of configuration data;indicating a first I/O pin of a first programmable device is to be used to output a handshaking signal during a configuration mode of the first programmable device, wherein the first programmable device is coupled to the source of configuration data;indicating a second I/O pin of a second programmable device is to be used to receive the handshaking signal from the first programmable device during a configuration mode of the second programmable device;configuring the first programmable device with configuration data transferred serially from the source; andconfiguring the second programmable device in response to the handshaking signal from the first I/O pin of the first programmable device and received at the second I/O pin of the second programmable device with configuration data from the source.
