Using ADSP-TS201S EZ-KIT Lite
Interrupt Pins
The ADSP-TS201S processor includes four interrupt pins (
IRQ3–0
) for
interaction with the running program. One external interrupt from each
processor is directly accessible through push buttons
SW4
and
SW5
on the
EZ-KIT Lite board. Interrupts are summarized in Table 1-4 . For more
information on configuring the interrupt pins, see the ADSP-TS201S Tig-
erSHARC Processor Hardware Reference .

FLAG Connection Description
FLAG0_A SW9
The
FLAG0
and
FLAG1
pins connect to the push buttons
to supply feedback for program execution. For instance,
you can write user input to trigger a routine when the
push button is pressed.

FLAG2_A LED4
The
FLAG2
and
FLAG3
pins connect to the LEDs to sup-
ply feedback during program execution.
