Operation sequence
1) Set up the power supply lines. (Note 1)
[+12V] (Orange)
[+5V] (Red)
[D5V] (Red)
[VVD1] (Red)
[VVD2] (Blue)
[AGND] (Black)
[DGND] (Black)
[VVSS2] (Black)
= +11.4 ∼ +12.6V
= +4.75 ∼ +5.25V (Note 2)
= +4.75∼ +5.25V (Note 3)
= +4.75∼ VVD2 (Note 4)
= VDD1∼ +5.25V (Note 4)
= 0V
= 0V
= 0V
Note:1. Each supply line should be distributed from the power supply unit.
2. JP9 (REG) should be open when the “+5V” jack is used.
3. JP8 (D-A) should be open when the “D5V” jack is used.
4. JP10 (VDD1) / JP11 (VDD2) should be open when the “VDD1” jack / “VDD2” jack are used
independently.
2) Set-up the evaluation modes, jumper pins and DIP-switches. (Refer next sections.)
3) Connect the PORT3 (µP-I/F) with PC by the enclosed 10-wire flat cable.
