Note: 1. The voltages V1, V2, and V5 must obey the relationships: VDD ≥ V1 > V2 > V5 > VEE, VDD – V2 ≤ 7V, V5 – VEE ≤ 7V.
2. When applying power, apply power to the LCD drive block after applying power to the logic block or apply power to both the blocks
simultaneously. When turning off power, turn off power to the logic block after turning off power to the LCD drive block or turn off power to both
the blocks simultaneously.
