Microprocessor Interrupts. Four external interrupts are used on the training board:
IRQ3*, IRQ5*, IRQ6*, and IRQ7*. You can assert the signals through the push
buttons on the training board or through the parallel control port.
Microprocessor Parallel Input/Output Port. The microprocessor has a general
purpose parallel input/output port (PORTA) that uses the upper eight address
lines. The port is used for general purpose (application defined) input and output
bits, serial clock bits, and serial data bits. Table 2–2 shows the bits of the port
and the corresponding signals. The PORTA signals are accessible on bus
interface connector (J180).
Table 2–2: PORTA signals
Bit Signal name Function
0 SCL Serial clock bit
1 SDA Serial data bit
2 CNTLIN1 Application defined input control bit
3 CNTLIN2 Application defined input control bit
4 CNTLIN3 Application defined input control bit
5 CNTLOUT1 Applicationdefinedoutputcontrolbit
6 CNTLOUT2 Applicationdefinedoutputcontrolbit
7 CNTLOUT3 Applicationdefinedoutputcontrolbit
Microprocessor Output Bits. The microprocessor has an output port that shares
the signal lines with the signal lines of the dedicated serial ports (A and B). Two
of the bits have specific uses. The OP4 bit generates the clears the external
trigger input. The OP6 bit generates the trigger output signal (EXTRIGOUT).
Both signals are active low signals.
Delay Line Memory. The delay line memory is a 16-bit read and write register to
demonstrate setup and hold timing violations during read operations. Data can be
written and then read from the same memory location; the data read should equal
the written data. When you program the delay line with a small delay, a setup
violation occurs during the read operation and the data read back will be different
than the written data. When you program the delay line with a large delay, a hold
violation occurs during the read operation and the returned data will be different
than the written data.

Programmable Delay Clock Select. The programmable delay clock select consists
of a serial shift register clocked by the microprocessor system clock. The input to
the shift register is the delayed shift register read strobe which is delayed in
multiples of the clock period. The input read strobe and three output bits of the
shift register are routed to a four-bit input multiplexer. The multiplexer selects
one of the four read strobes.
Programmable Delay Line. The programmable setup and hold delay line is an
eight-bit register with 256 programmable delay settings. The delay line delays
the read strobe to the delay line memory to demonstrate setup and hold timing
violations. Each delay count increment is a 0.5 ns time delay. The minimum
delay is 00 and the maximum is FF.

Hardware Features
2–4 TLA QuickStart Technical Reference Manual

Counter and Pattern Generator Signals. You can use the two 16-bit (or one 32-bit)
counter and pattern generators to demonstrate multiple logic analyzer and logic
scope capabilities. Both counter and pattern generators can be configured by
software. The counters can be programmed to count up or down. They can be
clocked by the 50 MHz oscillator or through an external trigger input.
Setup and Hold Trigger Signals. Use the setup and hold trigger signals to
demonstrate how logic analyzers can measure or trigger on setup and hold
signals. The setup and hold signals are generated by a four-bit counter. The
counter can be controlled by software to demonstrate setup violations or hold
violations.
Tapped Delay Line. Use the tapped delay line as basic pattern generator to show
signal skew, timing resolution, and sampling rates.
Burst Signal. Use the burst signal to demonstrate logic analyzer transitional
timing.

triggering.
Metastable Data and Clock Signals. Use the metastable data and clock signals to
demonstrate logic analyzer and oscilloscope setup and hold triggering.
Signal Sources Module

Hardware Features
TLA QuickStart Technical Reference Manual 2–5
Step Signal. Use the step signal to demonstrate analog bandwidth and triggering
of oscilloscopes and logic analyzers.
Runt Pulse and Missing Pulse Signal. Use the runt pulse and missing pulse signal
to demonstrate oscilloscope pulse triggering features. You can also use it to
demonstrate logic analyzer 4 ns counter/timers and time-qualified triggers.
Single-Shot Narrow Pulse Signal. Use the single-shot narrow pulse signal to
demonstrate analog bandwidths of oscilloscopes and logic analyzers. You can
also use this signal to demonstrate real-time sampling capabilities of the
oscilloscopes and logic analyzers.
Staircase Signal. Use the staircase signal to demonstrate the oscilloscope
acquisition modes and glitch detection.
The user interface module consists of the following elements:
A two-line by 16-character LCD display
Four push-button switches
A reset switch
Two 10-segment LED indicators
LCD Display. The main display device is a two line by 16 character LCD display.
The readout is controlled by software and by the four push-button switches.
The microprocessor communicates with the display by placing the upper eight
bits on the data bus. The LCD display has a register select (RS) bit. When the
RS bit is low, it selects the instruction register; when the bit is high, it selects the
data register.
Push-button Switches. The four push-button switches connect to the four external
interrupt lines of the microcontroller. The switches select and control the
programs in the training board. The LCD readout displays the push-button
switch functions. The right-most switch halts the program and asserts a
nonmaskable interrupt (NMI) signal to IRQ7.
Reset Switch. The Reset switch is a momentary push-button switch that provides
a system reset to the microcontroller.
