Table 2 Setup of power supply
* Each supply line should be distributed from the power supply unit.
AVDD1 and AVDD2 should be supplied as the same voltage level.
The difference of voltage level between AVDD1, AVDD2 and DVDD should be under 0.3V.
2) Set up the evaluation mode, jumper pins and DIP switches. (See the followings.)
