Table 26.5 Available Power-Supply Control-Sequence Periods at Typical Frame Rates
ONA, ONB, ONC, OFFD, OFFE, and OFFF are used to set the power-supply control-sequence
periods, in units of frames, from 0 to 15. 1 is subtracted from each register. H'0 to H'E settings
select from 1 to15 frames. The setting H'F selects 0 frames.
Actual sequence periods depend on the register values and the frame frequency of the display. The
following table gives power-supply control-sequence periods for display frame frequencies used
by typical LCD modules.

The display's frame frequency is 120 Hz. 1 frame period is thus 8.33 (ms) = 1/120 (sec).
The power-supply input sequence period is 7 frames because ONB setting is subtracted by 1.
As a result, the sequence period is 58.33 (ms) = 8.33 (ms) × 7.
