26.7. Advanced LCD Optimizations
The special function registers described in this section should be left at their reset value for most systems.
Some systems with specific low power or large load requirments will benefit from tweaking the values in
these registers to achieve minimum power consumption or maximum drive level.

Read = 00b. Must write 00b.
VLCD/VIO Supply Comparator Disable.
Setting this bit to ‘1’ disables the supply voltage comparator which determines if the
VIO supply is lower than VLCD. This comparator should only be disabled, as a
power saving measure, if VIO is internally or externally shorted to VBAT.
Read = 00b. Must write 00000b.
Must write 0x4B.
