Programmable FLAG Pins
1-10 ADSP-TS201S EZ-KIT Lite Evaluation System Manual
To program the flash memory with your boot code, first create a loader
file from your processor code. You set up the loader in Vi+
depending on how you plan to boot the flash. For information on creating
a loader file, refer to Vi+ online help and the
Vi+
Loader and Utilities Manual .
Next, the loader file must be programmed into the flash memory. This can
be done using the Vi+ Flash Programmer utility (see online
Help).
Programmable FLAG Pins
Each ADSP-TS201S processor has four programmable flag pins. Two flag
pins from each processor (
FLAG0
and
FLAG1
) allow interaction with the
running program through the use of a switch (
SW6–9
). The
FLAG2
and
FLAG3
pins from each processor are connected to LEDs (
LED3–6
).
After the processor is reset, the programmable flags are configured as
inputs. The direction of each programmable
FLAG
is configured in the
FLAGREG
register. If the flag is configured for output, the value of the flag
pin is set in the
FLAGREG
register. If the flag is configured for input, the
value on the flag pin is read from the
SQSTAT
register. Programmable flags
are summarized in Table 1-3 . For more information on how to configure
the programmable flag pins, see the ADSP-TS201S TigerSHARC Processor
Hardware Reference .
