CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (LCD Driver)
Cadence adjust-
ment of oscillation
frequency
In the S1C60N02 Series, the LCD drive duty can be set to
1/1 duty by software. This function enables easy adjust-
ment (cadence adjustment) of the oscillation frequency of
the OSC circuit.
The procedure to set to 1/1 duty drive is as follows:
Write "1" to the CSDC register at address "0FBH D3".
Write the same value to all registers corresponding to
COMs 0 through 3 of the display memory.
The frame frequency is 32 Hz (fOSC1/1,024, when fOSC1 =
32.768 kHz).
-
Even when l/3 or 1/2 duty is selected by the mask option, the
display data corresponding to all COM are valid during 1/1 duty
driving. Hence, for 1/1 duty drive, set the same value for all
display memory corresponding to COMs 0 through 3.
-
For cadence adjustment, set the display data corresponding to
COMs 0 through 3, so that all the LCD segments go on.
Figure 4.6.7 shows the 1/1 duty drive waveform (1/3 bias).
Figure 4.6.8 shows the 1/1 duty drive waveform (1/2 bias).
