programming information
Texas Instruments programmable logic devices can be programmed using widely available software and
inexpensive device programmers.
Complete programming specifications, algorithms, and the latest information on hardware, software, and
firmware are available upon request. Information on programmers capable of programming Texas Instruments
programmable logic is also available, upon request, from the nearest TI field sales office, local authorized TI
distributor, or by calling Texas Instruments at (214) 997-5666.
preload procedure for registered outputs (see Figure 1 and Notes 2 and 3)
The output registers can be preloaded to any desired state during device testing. This permits any state to be
tested without having to step through the entire state-machine sequence. Each register is preloaded individually
by following the steps given below.
Step 1.
With VCC at 5 volts and Pin 1 at VIL, raise Pin 13 to VIHH.
Step 2.
Apply either VIL or VIH to the output corresponding to the register to be preloaded.
Step 3.
Pulse Pin 1, clocking in preload data.
Step 4.
Remove output voltage, then lower Pin 13 to VIL. Preload can be verified by observing the
voltage level at the output pin.
