¡ Semiconductor
OPERATING MODE SETTING
There are two types of video mode settings.
1. External pin mode: direct setting from dedicated pins
2. Register setting mode: specification by internal register settings
These modes can be switched by the mode register MRA[0].
The reset state (default) is the external pin mode.
The following registers can be set in the external pin mode.
Note:
