5.0. JTAG Connector
JTAG ICE is an emulator used for AVR microcontrollers with built-in JTAG interface (Mega AVR microcontrollers). JTAG ICE is primar-
ily intended for work with the AVR Studio program. The JTAG connector built into AVR microcontrollers is a modifi ed version of the
original JTAG interface. It enables contents of internal EEPROM and FLASH memory to be changed (programming microcontroller).
Figure 5-1: JTAG connector
The JTAG connector is directly connected to the microcontroller pins so that it doesn’t depend on jumpers J7 and J8 settings which
otherwise have to be performed when using AVRprog and AVRISP programmers.
6.0. Clock Oscillator
There is a clock oscillator provided on the board used as a clock signal external source. The quartz crystal used for the purpose of
stabilizing clock frequency is plugged into the appropriate socket and therefore can always be replaced with another one. Its maximum
value depends on the maximum operating frequency of the microcontroller.
