Specify a ddr es s source

This parameter directs the block to get the address for the

variable either from an entry in Address or from the input port to

the b lock. Select either

Specify via dialog or Input port from

the list. Selecting

Specify via dialog activates the Add ress

parameter for you to enter the address for the variable.

When you select

Input port, the port label on the block changes

&src, indicating that the block expects the address to come

from the input port. Being able to change the a ddress dynamically

lets you use the block to copy different variables by providing the

variable address from an upstream block in your model.

Source code symbol

Specify the symbol (variable) in the source code symbol table

to copy. The symbol table for your program must include this

symbol. The block does not verify that the symbol exists and uses

valid syntax. Enter a string to specify the symbol exactly as you

use it in your code.
