5.6.5 FPDAT Signals in LUT Bypass Mode (TFT panel, 12-bpp mode)
Figure 26.
When a pixel data is 0xc51 (R = 0xb, G = 0x5, B = 0x1), for example, the FPDAT signals will be config-
ured as follows:
FPDAT15 = High (1)
FPDAT10 = Low (0)
FPDAT4 = Low (0)
FPDAT14 = High (1)
FPDAT9 = High (1)
FPDAT3 = Low (0)
FPDAT13 = Low (0)
FPDAT8 = Low (0)
FPDAT2 = Low (0)
FPDAT12 = Low (0)
FPDAT7 = High (1)
FPDAT1 = High (1)
FPDAT11 = Low (0)
FPDAT6 = Low (0)
FPDAT0 = Low (0)
FPDAT5 = Low (0)
FPDAT[23:16] = Low (0)

5.6.6 FPDAT Signals in LUT Bypass Mode (TFT panel, 16-bpp mode)
Figure 26.
When a pixel data is 0x5b37 (R = 0xb, G = 0x19, B = 0x17), for example, the FPDAT signals will be con-
figured as follows:
FPDAT15 = Low (0)
FPDAT10 = Low (0)
FPDAT4 = High (1)
FPDAT14 = High (1)
FPDAT9 = High (1)
FPDAT3 = Low (0)
FPDAT13 = Low (0)
FPDAT8 = High (1)
FPDAT2 = High (1)
FPDAT12 = High (1)
FPDAT7 = Low (0)
FPDAT1 = High (1)
FPDAT11 = High (1)
FPDAT6 = Low (0)
FPDAT0 = High (1)
FPDAT5 = High (1)
FPDAT[23:16] = Low (0)
