„ Operation sequence
1) Set up the power supply lines.
1-1) AVDD, PVDD and TVDD are supplied from the regulator. (TVDD jacks should be opened.JP5 should be
selected “REG”, and JP7 should be “short”.). See “Other jumper pins set up (page 4)”. <default>

Note. Each supply line should be distributed from the power supply unit.
SVDD voltage level must be larger than “AVDD – 0.3V” and “PVDD – 0.3V”.
2) Set up the jumper pins. (See the followings.)
3) Power on.
The PDN pin must keep “L” until all power supply pins are supplied.
SW1 can be set to “H”, after all power supply pins are supplied.
