FlashLINK. Email STMicroelectronics at
for technical
assistance.
The PSD4256G6Vcan be re-programmed using the FlashLINK JTAG
programming cable available from STMicoreclectronics (
www.st.com/psd
)
for approximately $59. FlashLINK plugs into any PC parallel port. The
PSDsoft Express development software is required to modify the
DSM2150 configuration and to operate the FlashLINK cable. PSDsoft
Express can be downloaded at no charge from

Using LEDs and Push Buttons
The EZ-KIT Lite provides four push buttons and six LEDs for gen-
eral-purpose IO.
The six LEDs, labeled
LED4
through
LED9
, are accessed via some of the
general-purpose IO pins of Flash memory interface. For information on
how to program the pins, see
“Flash General-Purpose IO” on page 2-7
.
The four general-purpose push button are labeled
SW4
through
SW7
. A sta-
tus of each individual button can be read through programmable flag (PF)
inputs,
PF8
through
PF11
. A PF reads “
1
” when a corresponding switch is
being pressed-on. When the switch is released, the PF reads “
0
”. A connec-
tion between the push button and PF input is established through the
SW9
DIP switch. See
“Push Button Enable Switch (SW9)” on page 3-12
for
details.
An example program is included in the EZ-KIT installation directory to
demonstrate the functionality of the LEDs and push buttons.
