Board Setup and Software Installa-
tion Instructions
1. At the appropriate disk drive prompt (A:\) type
Install
to automatically copy demo files to the C: drive.
NOTE: This demo software requires Microsoft QBa-
sic or equivalent to run. Make sure the directory
containing qbasic.exe is in the DOS path statement,
or move the demo files to a directory containing Ba-
sic.
2. Connect a +5 Volt power supply to the board: RED =
+5V, BLACK = ground.
3. Remove all software keys from the computer parallel
port.
4. Connect the supplied interface cable to the parallel
port (DB25 connector) and to the demo board (6-pin
connector). Make sure the cable is facing away from
the board – pin 1 is the red wire.
5. Connect the clock outputs to the target application
board with a twisted-pair cable.

1. Type
FS6011
at the C:\FS6011 prompt to run the
Qbasic-based demo program.
Demo Program
2. The following banner should appear:
****************************************

* FS6011 Utility Program *
* *
* PRESS ANY KEY TO CONTINUE..... *
* *
****************************************
3. After pressing any key, a menu should appear con-
taining a list of the program hot keys, a message that
the computer parallel (LPT1) port was found, and the
address at which the port was found.

***********************
Refer to Table 18 for a description of each hot key.
4. To change the frequency of the desired clock, press
the appropriate hot key. The keys are
not
case sensi-
tive.
5. Refer (in the FS6011 data sheet) to Table 3 and
Table 4 for ACLK frequencies, Table 5 for UCLK fre-
quencies, and Table 6 for PCLK frequencies.
6. Observe the response to the hot key selection. Re-
peated pressing of the same key will scroll through
the entire range of frequencies for the selected clock,
returning to the initial frequency.
7. Pressing a hot key strobes a 15-bit message to the
demo board via the interface cable. The response to
the key selection is shown below:
Writing...
(0x000) Binary: LSB 000000000000000 MSB
where the numbers are the data in hex and binary.
Note that the PCLK frequency is changed by directly ad-
dressing pins 4 and 5 (PSEL0 and PSEL1) of the device.
Therefore the hot key response message will be un-
changed when selecting the (
P
)CLK hot key. Press
X
to
exit the demo program.
