26.4.3
As an LCD segment is electrically only a capacitor, cur-
rent is drawn only during the interval where the voltage
is switching. To minimize total device current, the LCD
internal reference ladder can be operated in a different
power mode for the transition portion of the duration.

(Register 26-7).

The LCDRL register allows switching between two
power modes, designated ‘A’ and ‘B’. ‘A’ Power mode
is active for a programmable time, beginning at the
time when the LCD segments transition. ‘B’ Power
mode is the remaining time before the segments or
commons change again. The LRLAT<2:0> bits select
how long, if any, that the ‘A’ Power mode is active.
Refer to Figure 26-4.
To implement this, the 5-bit prescaler used to divide
the 32 kHz clock down to the LCD controller’s 1 kHz
base rate is used to select the power mode.
