† Although timing diagrams illustrate the logical function of the TFT mode, static timings apply to all supported modes of operation. Likewise,
LCD.HS, LCD.VS, and LCD.AC are shown as active-low, but each may optionally be configured as active-high.

† Delays for HSW (LCD.HS Width), VSW (LCD.VS Width), VFP (Vertical Front Porch), HFP (Horizontal Front Porch), HBP (Horizontal Back Porch)
and PPL (Pixels per Line) are programmable in number of LCD.PCLK cycles via the LCD configuration registers.
