* After transfer from normal to standby, the respective state becomes effective after normal output for the 1V period.
b) Transfer/return to each mode
• Transfer/return between normal and standby modes is acknowledged with the vertical synchronous signal.
• Transfer/return between standby and sleep modes is changed over each time the serial data is transmitted.
• Transfer/return between normal and sleep modes cannot be made directly.
Be sure to carry out changeover via the standby mode.
