2) Connect the Multilink to the target via its ribbon cable. Make sure that the ribbon cable is plugged
into the target with the proper orientation. PIN 1 is denoted by the red stripe running down the
ribbon cable.
3) Connect the Multilink to the PC via a USB extension cable. The Blue LED on the Multilink should
become lit.
4) Turn the target power on. The Yellow LED on the Multilink should become lit.
Before disconnecting the setup, turn the target power off.
7.0 Startup Reset Sequence
In order to use the Background Debug Mode of the microcontroller, it is initialized into debug mode via a
reset sequence.
This is accomplished by P&E’s software via the following reset sequence:
RST 5msec
BKGD 10msec 20msec
a) Initially the BKGD (pin-1) and Reset (pin-4) are pulled low.
b) After 5 milliseconds, the RESET (pin-4) goes high.
c) After 10 milliseconds, the BKGD (pin-1) goes high.
d) Wait for 20 milliseconds, followed by activities on BKGD (pin-1).
8.0 Interface Libraries
One of the products P&E produces is a set of interface libraries which allows the user to directly control the
USB HCS08/HCS12 Multilink from any Windows Development Environment which can interact with a
DLL. The interface libraries come with examples for controlling the Multilink interface from Microsoft
Visual C as well as Borland Delphi. Details of the libraries for the RS08 may be found at P&E's RS08
Product Page. Details of the libraries for the HCS08 may be found at P&E's HCS08 Product Page. Details of
the libraries for the HC12 and HCS12 may be found at P&E's HC(S)12 Product Page
.
9.0 Firmware Updates
The latest version of the firmware for the Multilink interface is included in P&E software development kits.
When the debugger or programmer is run, if it detects that the Multilink interface firmware needs to be
updated, it will ask the user’s permission to do this. If granted, the update happens automatically.
Alternately, the latest version of the firmware may be downloaded from the “Firmware Updates” section of
the “Support Center” located at http://www.pemicro.com.
