◆Register map（1/2）
The data in every register is updated in 3 ways which are showed below.
① Updated to the newest data immediately when the data is written.
② Updated to the newest data when the next VSYNC or VSYNC_REG signal rises up (positive-edge trigger).
③ Updated to the newest data when the next PWM signal rises up (positive-edge trigger).
