MSM6794
When the original oscillation frequency is 350kHz and the frequency dividing ratio is 1, the
frame frequency is about 80Hz. When the display data register is written/read, the busy time
is a maximum of 8 original oscillation clocks. If the original oscillation frequency is increased
to shorten the busy time, the frame frequency increases in proportion to the original
oscillation frequency. In this case the frequency dividing ratio must be changed so that the
frame frequency falls in the range of 60 to 100Hz. For details on the relation between original
oscillation frequency and frame frequency, see "Original Oscillation Frequency and Frame
Frequency".
(D4, D3, D2) = (1, 1, 0) and (1, 1, 1) are combinations which Oki uses for testing.
If these combinations are used by the user, the operation of this IC is unpredictable.
The value of this register does not change even if the
RESET
pin is set to "L".
Once frame frequency is set after power is turned on, the value cannot be changed. To change
the frame frequency, set it again according to the power-on flowchart. See "Power-on
Flowchart".
(5) D1, D0 DUTY (Display Duty Select)
These bits select the display duty. Correspondence between each bit and display duty is
shown in the table below.
