FTE[2:0]: FTE bits specifies the rising position of FLM during display operation with DOTCLK (DM =
2âh1) when LTPS = 1. The setting of this register setting is invalid when LTPS = 0. In this case, the rising
position of FLM is at a reference point.
FWE[5:0]: FWE bits specifies the width of âHighâ of FLM during display operation with DOTCLK (DM
= 2âh1) when LTPS = 1. The register setting is invalid when LTPS = 0. In this case, the width of âHighâ
of FLM is 1H.
See the figures (page 66, 67) with regard to how the signal waveform of each gate driver and LTPS LCD
panel interface are controlled by these settings.

Note 1) The clocks in the tables are DOTCLK / division ratio for the 1H period, measured from a reference
point. The reference point is the position where SFTCLK rises when the rising position of SFTCLK is
set to 0 clock.
