LCD_DATA[15:0]
LCD_WR_RWn
The LCDIF has flexible pin and strobe timings which enable it to optimally support a wide
range of LCDs. The minimum cycle time is two CLK_DIS_LCDIFn cycles (TDS=TDH=1).
For example, this results in a maximum LCD data rate of 12 MB/s when CLK_DIS_LCDIFn
is 24 MHz. TDS and TDH are 8-bit values, so the minimum LCDIF period is 510
