37. z For 16MHz 2MHz is the limit It is not recommended to operate at exactly 14 of the target frequency especially when programming fuses as this can cause them to become incorrectly set and possibly render the AVR useless unless parallel programming is available Note that many AVRs come from the factory with the clock source set to the internal 8MHz oscillator and with the CKDIV8 fuse programmed resulting in a clock speed of 1MHz In these cases the ISP programming speed should be set to 125KHz or less until CKDIV8 is unprogrammed and power cycled For all modes the 8MHz clock output can be connected to the target clock input and used as a recovery clock This is useful for example to allow resetting of fuses that were mis configured to use an external clock when intending to use a crystal or internal oscillator The MT UX supports target devices operating at 3 0V to 5 5V The voltage of the outputs from the MT UX is determined by the voltage present on the Vcc power input pin This voltage is usually provided by the MT UX which can supply either 5 0V or 3 3V Alternatively the target board can supply this voltage In either case Vcc and ground must be connected to the target board Consult the Hardware section for details All outputs from the MT UX have 300ohm series resistors that limit current and control overshoot and ringing July 21 2012 16 http www mattairtech com MT X4 UX Manual Using Atmel Studio AVR Studio Star
