EXTENDED COMMANDS
These commands are used, in addition to basic commands, to trigger the enhanced features, on top
of general ones, designed for the chip.
9.29 Set TC value
This command is to set 1 out of 8 different temperature coefficients in order to match
various liquid crystal temperature grades.
9.30 Enable internal oscillator resistor
This command is used to enable/disable the internal oscillator. The value of the internal
oscillator resistor is 520k
.
9.31 Enable Frame Frequency setting
This command is used to enable/disable set frame frequency. The frame frequency can
be tuned when enable internal oscillator resistor and frame frequency setting.
Figure 9 – Sequence for setting frame frequency
9.32 Set COM Scan Sequence
This command is used to select one of four sets of COM Scan sequence.
9.33 Set Frame Frequency setting
This command specifies the frame frequency so as to minimize the flickering due to the
ac main frequency. The frequency is set to 90Hz(typical) at 128 mux after enabled internal
oscillator resistor.
Yes
Enable internal oscillator resistor (0xF8; 0XF0)
Enable Frame Frequency setting (0xFB; 0X08)
Set the Frame Frequency (0x82; 0x00~0x70)
