hi......I want to readout data from ST7FL39 CPU....for that I am using RLINK device.....after installation software to PC I check my device serial number with a help RFLASHER7 ...it's ok. To readout data from ST7FL39, used RLINK -ADP-ST7-STM8-V2.1.....according to this adapter for ICC jumper must be connected.....after connecting ICC, I used 10 pin header with 1st pin no connection, 2nd pin ICC DATA, 3rd pin GND, 4th pin ICC CLK, 6th pin RESET, and 8th pin V+......and there is two more pin 7th pin Vcc_TARG(this V+ supply use for what I don't understand and 6.8 V zinged diode to connect the pin 7 and GND). And other pin 9 we must put external crustal 12MHz or we have to joint  12MHz header I don't understand . After these 2pin 7 and 9 , I don't connect and try to read the programmer say problem while downloading monitor, what does this mean please help me!

hi....to programm i used software ST VISUAL PROGRAMMER....when i used Rlink to read STM8S103K3 with SWIM cinnection i can read and write what i want.......when i used ICC,to read  ST7FL39 on same platefrom, software display this massege"PROBLEM WHILE DOWNLODING MONITOR'  i don't understand what does this mean?..... about ICC conection on 10th pin fimale connecter 1,3,5,10 are GND.....2 ICCDATA...4 ICC CLK....6 RESET....

&7pin is used VCC-TARGET.....my target device complitly run with 12V DC...i have to give that 12V supply on that pin?.......about 9th pin OSC, they recomend 12MHz cristal to put....whta does this mean...i have to put external 12MHz crital on ST7FL39 CPU's 20 leg? or i have to just connect pin for 12MHz, which is given n adapter? please help
