U4.0 to U4.3 provide backplane signals in LCD Mode. To
operate any ports as LCD segment driver it is necessary to
switch all these ports to LCD mode. This has to be done by
setting flags U4MODE.L0 through U4MODE.L3.
As backplane ports U4.0 to U4.3 require no segment data
setting, SG0_0 through SG3_3 bits are not available in U4
registers.
