DUTY2 to DUTY0
(bit 2 to 0)
The DUTY2 to DUTY0 bits are used to specify the duty in 5 steps (1/1 to 1/5). The numbers of
commons/segments are determined according to the duty setting.

FRM1-FRM0
(bit 6, 5)
The FRM1 to FRM0 bits are used to select a frame frequency of the LCD drivers.
The reference frequency of a frame frequency (LLSCLK = 32.768 kHz) is selectable from 64 Hz, 73 Hz, 85 Hz,
or 102 Hz.
