2.2 Display Interface
2.2.1 Display Output Format
2.2.2 Output Synchronous Signals
OKI Semiconductor
The TFT-LCD mode or TV mode can be selected as a display output format.
• TFT-LCD mode
• TV mode
[Control Registers]
• DOFMT
• TVSTD
The functions of the output synchronous signals partially vary with the display output format.
