DBL_SB: Chooses the size of LUT for Table 06h.
0 = (Default) Single LUT of 32 bytes.
1 = Double LUT of 16 bytes.
UP_LOWB: Determines which 16-byte LUT is used if DBL_SB = 1. If DBL_SB = 0, the value of this
bit is a don’t care.
0 = (Default) Chooses the lower 16 bytes of Table 06h (Registers 80h-8Fh).
1 = Chooses the upper 16 bytes of Table 06h (Registers 90h-9Fh).
