In 16-bpp mode, there is a total of two lines of pattern, each line with eight pixels as illustrated in Table 6-18. In 32-bpp
mode, there is only one line of pattern with eight pixels. The ordering of the registers in the line from left to right is as fol-
lows:
1)
GP_PAT_COLOR_5
2)
GP_PAT_COLOR_4
3)
GP_PAT_COLOR_3
4)
GP_PAT_COLOR_2
5)
GP_PAT_COLOR_1
6)
GP_PAT_COLOR_0
7)
GP_PAT_DATA_1
8)
GP_PAT_DATA_0.
