User`s manual
• Use only attached ISP cable. When you use other ISP 
cable (other material, length…), programming may occur 
unreliable. 
• 865  can  supply programmed device (pin 1 of ISP 
connector) and target system (pin 5, 13, 14 of ISP 
connector) with limitation (see Technical specification / ISP 
connector), but target system cannot supply 865. 
• 865 apply programming voltage to target device and 
checks his value (target system can modify programming 
voltage). If the programming voltage is different as 
expected, no action with target device will be executed.

Self test and Calibration 
If you feel that your programmer does not react according to
