VII LCD CONTROLLER BLOCK: LCD CONTROLLER

Other Settings

FPSHIFT mask

When a color passive LCD panel is used, FPSHIFT (shift clock) can be turned on or off during the non- display period using FPSMASK (D2)/LCDC mode register 0 (0x39FFE1).

FPSMASK = "1": Turned off

FPSMASK = "0": Turned on (default)

FPSMASK can only be set when LDCOLOR (D5)/LCDC mode register 0 (0x39FFE1) = "1" (color panel). Otherwise, FPSMASK has no effect.

MOD rate

The period during which the MOD signal is switched can be set using the MODRATE[5:0] (D[5:0])/MOD rate register (0x39FFEB).

MODRATE = "0x0":MOD signal switched at a period of the FPFRAME signal (default)

MODRATE = other than "0x0": Switched at a period of MODRATE + 1 FPLINE pulses

Repeating of the FRM pattern

This setup item is provided for EL panels. Whether the frame-rate modulation pattern is to be repeated every 0x40000 frames (counted by the internal frame counter) can be set using FRMRPT (D2)/LCDC mode register 1 (0x39FFE2).

FRMRPT = "1": FRM pattern repeated

FRMRPT = "0": FRM pattern not repeated (default)
