(a) When the V0 voltage regulator internal resistors are used
Through the use of the V0 voltage regulator internal resistors and the electronic volume
function the liquid crystal power supply voltage V0 can be controlled by commands alone
(without adding any external resistors), making it possible to adjust the LCD brightness. The
V0 voltage can be calculated using equation A over the range where V0<VOUT.

The
α is set to 1 level of 64 possible levels by the electronic volume function depending
on the data set in the 6-bit electronic volume register. Table 7 shows the value for
α
depending on the electronic volume register settings.
