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.
asynchronous preload procedure for registered outputs (see Figure 1 and Note 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.
Step 2.
Step 3.
Step 4.
With V
CC
at 5 volts and Pin 1 at V
IL
, raise Pin 11 to V
IHH
.
Apply either V
IL
or V
IH
to the output corresponding to the register to be preloaded.
Lower Pin 11 to 5 V.
Remove output voltage, then lower Pin 11 to V
IL
. Preload can be verified by observing the
voltage level at the output pin.
