1.0 Introduction
P&E鈥檚 USB HCS08/HCS12 MULTILINK Interface provides access to the Background Debug Mode (BDM)
on Motorola HCS08, HC12 and HCS12 microcontrollers. It is the hardware interface between a USB port on
a Windows 2000 or XP machine and the standard 6 pin 鈥淏erg鈥?debug connector on the target. By using the
USB HCS08/HCS12 MULTILINK, the user can take advantage of the background debug mode to halt
normal processor execution and use a PC to control the processor. The user can then directly control the
target鈥檚 execution, read/write registers and memory values, debug code on the processor, and program
internal or external FLASH memory devices. The pinouts of the connector as specified by Motorola are:
BKGD 1
