Warnings:
• When you use 844USB as ISP programmer, don’t insert device to ZIF socket.
• When you program devices in ZIF socket, don’t insert ISP cable to ISP connector.
• Use only attached ISP cable. When you use other ISP cable (other material, length…),
programming may occur unreliable.
• 844USB can supply programmed device only, but target system cannot supply
844USB.
• 844USB 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.
