Chapter 3 – Schematic diagram

For U1(20pins) and U2 (28pins), all the pins are opened. They are not connected to any
XTAL circuit. A wire can be use to connect the XTAL1 and XTAL2 pin to the external
XTAL circuit on board.

The /RESET pin of U1(20pins) and U2 (28pins) are also not connected to the external
reset circuit on board.
