Gives the XS1 port-to-pin mapping, which is interpreted as follows: The ports are multiplexed, allowing the pins to beД¬onfigured for use by ports of different widths. Ports and to construct links to other devices over which channels areД®stablished. On XS1 devices, pins are used to interface with external components via This can be changed by the function set_port_sample_delay() By default the portвЂ™s sampling edge is the rising edge of clock. On the falling edge of the clock the ready-out port is driven high if data is output on that edge, otherwise it is driven low. Outputs are driven on the next falling edge of the clock where the previous value read from the ready-in port was high. The ready-in port is read on the sampling edge of the buffered port. The port drives the initial value on its pins until an output statement changes the value driven. If the ready-in or ready-out ports are not 1-bit ports an exception is raised.

If the oscillator frequency is specifed and none of the manual PLL attributesДЄre provided, automatic configuration is used. Information on the PLL dividers can be found in xCORE frequency control The tools use these values to set the PLL registers and reference clock divider. Provided and the PLL oscillator input frequency must be specifed. PllMultiplierStageReg, PllDividerStageTwoReg and RefDiv must be If manual configuration is used, the attributes PllDividerStageOneReg, OscillatorSrc attribute must not be provided, and vice versa. If the Oscillator attribute is provided the The PLL oscillator input frequency may be specifed using the Oscillator or If any of the first threeДЄttributes are provided, none of the last four attributes may be PllDividerStageOneReg, PllMultiplierStageReg, Or can be configured manually using the attributes SystemFrequency, PllFeedbackDivMin and ReferenceFrequency, The PLL registers can be configured automatically using the attributes SystemFrequency / RefDiv = ReferenceFrequency Defaults to 1 if unset.ДЄ reference clock frequency, specified as a number followed by either The minimum allowable PLL feedback divider. The system frequency, specified as a number followed by either MHz, The name of the node which supplies the PLL oscillator input. The PLL oscillator input frequency, specified as a number followed by Maps the node to an element in the package file. The routing identifier on the xCONNECT Link network. This attribute is only valid on nodes with type xml in the path specified byДЄssociates the node with a xCORE Tile indentifer specified in aДeclaration. The tools search for the fileД¬onfig_ type. Otherwise the type specifies the name of an XML file thatДescribes the node.

If type is periph:XS1-SU the node is a XS1-SU peripheral node.

All node names in the network must be unique.
