The following figure shows the graphic representation of a function when the following
function is defined: Function name = TEST, number of inputs = 4, number of address
inputs = 1, and number of outputs = 4.

Fig 3.6 Graphic Representation of a Function 1 (Example)

Note: 1. After creating the graphic representation of the function, define the

data types of the function inputs, outputs, and address inputs.

2. Three data types can be defined: Bit, integer, and double integer.

3. When the data types are defined, the system automatically allo-

cates inputs to the X registers, outputs to the Y registers, and
address inputs to the A registers.
