6.30 Serial RGB Output
BIT1612 內建Serial RGB輸出介面,從可以SRGB[8:1] (Pin52~Pin45)輸出數位RGB信號,從RTSx輸出HSYNC
、VSYNC、DE等信號,從SRGB_CLK(Pin 54) 輸出Clock信號,符合多種LCD Panel的Serial RGB輸入規格。詳
細規格請參考
Table 6-56、Figure 6-36 及 Figure 6-37。

6.31 BIT1690 Interface
BIT1690 為 3-Channel Video DAC,可以驅動類比LCD Panel,BIT1612 內建與BIT1690 輸入相容的介面,
透過BIT1612 的Register可以直接對BIT1690 進行控制。控制方式請參考
Table 6-57 及 Figure 6-38 和BIT1690
Data Sheet。需特別注意的是,在 0x0F5 的部份,只有當ADDR[2:0]的值有改變時,命令才有效。
