The microcontroller can also be programmed with the JTAG programmer, Figure 3-3. In addition, this programmer can
also be used to test the operation of the microcontroller.
In order to enable the JTAG programmer to be used, it is necessary to place jumper J1 in the ENABLE position, Figure
3-5. If the JTAG programmer is not used for programming, jumper J1 should be removed from the board, Figure 3-6.
