Selection of 5 V/3.3 V power supply
How to supply VCC of this board to the AVCC terminal of evaluation MCU
How to supply VCC of this board to the AVR terminal of evaluation MCU
How to supply VCC of this board to the AVCC terminal and AVR terminal of evaluation MCU
Selection of the supply level to the MOD terminal of evaluation MCU
Connection of the capacitor between the Cpin terminal and the VSS terminal of evaluation MCU
The details of a setup of 5 V/3.3 V power supply jumper plug selection (JP3/JP4) are shown in Table
5. When you supply the power supply from the external power supply input terminals TP2 (VCC)
and TP3 (VSS), please open the power supply selection jumper plug (JP3/JP4) of 5 V/3.3 V.
Note : Be sure to give a setup of JP3/JP4 as the same. When a different setup is performed,
When you supply VCC of this board to the analog power supply terminal (AVCC) of Evaluation
MCU built in the MCU board,please connect an attachied jumper plug to this board at an AVCC -
VCC supply jumper plug (JP5). However, when you supply the AVCC power supply from an exter-
nal power supply input terminal (AVCC), please give as open.
When you supply VCC of this board to the analog standard voltage terminal (AVR) of Evaluation
MCU built in the MCU board,please connect an attachied jumper plug to this board at an AVR -VCC
supply jumper plug (JP6). However, when you supply the AVR standard voltage from an external
power supply input terminal (AVR), please give as open.
When you supply VCC of this board to the analog power supply terminal (AVCC) and analog stan-
dard voltage terminal (AVR) of Evaluation MCU built in the MCU board,please connect an attachied
jumper plug to this board at an AVSS - VSS connection jumper plug (JP7). However, when you sup-
ply an AVCC power supply from the terminal (AVCC) for an external power supply input, or when
you supply AVR standard voltage from the terminal (AVR) for an external power supply input, be
sure to give as open.
The supply level to the mode terminal (MOD) of Evaluation MCU carried in the MCU board is cho-
sen with an MOD selection jumper plug (JP8). Details are shown in Table 6. Be referred to as "short"
of a jumper plug, and give an MOD terminal state as an "L level".
Between the Cpin terminal of the evaluation MCU built on the MCU board, and a VSS terminal,
when you connect a capacitor, please mount the capacitor to the socket for C terminals (CN3).

the power supply which is 5 V/3.3 V short-circuits, and has a possibility of becoming
the cause of the operation which is not right, or failure.
