1. NC 3 4 RESET NC 5 6 VDD Usage Of The USB BDM MULTILINK Interface The USB BDM MULTILINK can communicate with an RS08 HCS08 HC12 HCS12 or ColdFire V1 processor P amp E s software packages will automatically detect the proper communication rate to establish a connection with the target For HC12 HCS12 devices the BDM communication speed may be set instead of being auto detected by setting the value of the IO_DELAY_CNT variable The proper IO_DELAY_CNT may be calculated by the equation IO_DELAY_CNT 120000000 Fbus 1 where Fbus is the bus frequency in hertz Note RS08 and HCSO8 frequencies are always detected automatically The Multilink interface will work with targets whose processor power supply is in the range of 1 6V to 5 25V The Multilink interface derives its power from the USB port and as such draws less than 1mA from the target The USB BDM MULTILINK has a female type B USB connector Use a Type A to Type B USB extension cable to connect the interface to the PC The USB BDM MULTILINK is a USB device If a USB Hub is used it must be a self powered hub i e with its own power supply By default the USB protocol used is 2 0 There are two LEDs which protrude through the housing of the USB BDM MULTILINK interface The Blue LED indicates that the Multilink interface is powered and running The Yellow LED indicates that target power has been detected The 6 pin ribbon cable which allows connection to the target de
