Section 25 LCD Controller
1. The PALEN bit in the LCDC color palette register is 0 (initial value); normal display operation
2. Access LDPALCR and set the PALEN bit to 1; enter color-palette setting mode
3. Access LDPALCR and confirm that the PALS bit is 1.
4. Access LDPR00 to LDPRFF and write the required values to the PALD00 to PALDFF bits.
5. Access LDPALCR and clear the PALEN bit to 0; return to normal display mode
0 is output on the LCDC display data output (LCDD) while the controller is in color palette setting
mode.
PALDnn color and gradation data should be set as above, using 256-gradation values for R, G, B,
and M.
For a color display, PALDnn [23:16], PALDnn [15:8], and PALDnn [7:0] respectively hold the R,
G, and B data. Although the bits PALDnn [18:16], PALDnn [9:8], and PALDnn [2:0] exist, no
memory is associated with these bits. PALDnn [18:16], PALDnn [9:8], and PALDnn [2:0] are
thus not available for storing palette data. The numbers of valid bits are thus R: 5, G: 6, and B:
5.24-bit (R: 8 bits, G: 8 bits, and B: 8 bits) data should, however, be written to the palette-data
registers. When the values for PALDnn [23:19], PALDnn [15:10], or PALDnn [7:3] are not 0, 1s
should be written to PALDnn [18:16], PALDnn [9:8], or PALDnn [2:0], respectively. When the
values of PALDnn [23:19], PALDnn [15:10], or PALDnn [7:3] are 0, 0 should be written to
PALDnn [18:16], PALDnn [9:8], or PALDnn [2:0], respectively. Then 24 bits are extended.
Grayscale data for a monochromatic display should be set in PALDnn [7:3]. PALDnn [23:8] are
all ‘don’t care’. When the value in PALDnn [7:3] is not 0, 1s should be written to PALDnn [2:0].
When the value in PALDnn [7:3] is 0, 0s should be written to PALDnn [2:0]. Then 8 bits are
extended.
