LogiBlox Functions

The following LogiBLOX modules can be used in schematics

Module	Description
ACCUMULATOR	Adds data to or subtracts it from the current value stored in the accumulator register
ADDER/SUBTRACTOR	Adds or subtracts two data inputs and a carry input
CLOCK DIVIDER	Generates a clock pulse whose period is a multiple of the clock input period
COMPARATOR	Compares the magnitude or equality of two values
CONSTANT	Forces a constant value onto a bus
COUNTER	Generates a sequence of count values
DATA REGISTER	Captures the input data on active CLOCK transitions
DECODER	Routes input data of 1-of-n lines on the output port
INPUT/OUTPUT	Connects internal and external pin signals
MULTIPLEXER	Type 1, Type 2 - Routes input data on 1-of-n lines to the output port
PAD	Simulates an input/output pad
SHIFT REGISTER	Shifts the input data to the left or right
SIMPLE GATES	Type 1, Type 2, Type 3 -; Implements the AND, INVERT, NAND, NOR, OR, XNOR, and XOR logic functions
TRISTATE BUFFER	Creates a tristate internal data bus. Not available on XC9500XL devices
