Registers Each word location contains two palette entries, which means that 128 word locations are used for the palette. When configured for little endian byte ordering, bits [15:00] are the lowernumbered palette entry and bits [31:16] are the higher-numbered palette entry. When configured for big endian byte ordering, bits [31:16] are the lowernumbered palette entry and bits [15:00] are the higher-numbered palette entry. 31 30 29 Int0 15 28 27 26 25 24 23 B[4:0] 14 13 12 21 20 19 G[4:0] 11 10 9 8 7 B[4:0] Int1 22 18 17 16 1 0 R[4:0] 6 5 G[4:0] 4 3 2 R[4:0] Register bit assignment Bits Access Mnemonic Reset Description D31 R/W Int0 N/A Intensity/unused Can be used as the least significant bit of the R, G, and B inputs to a 6:6:6 TFT display, doubling the number of colors to 64K, where each color has two different intensities. D30:26 R/W B[4:0] N/A Blue palette data For STN color displays, only the four most significant bits (04:01) are used. Not used for monochrome displays. D25:21 R/W G[4:0] N/A Green palette data For STN color displays, only the four most significant bits (04:01) are used. Not used for monochrome displays.
