When using partial display function, the display duty can be selected among 1/16, 1/24, 1/32, 1/40,
1/48, 1/56, 1/64, 1/72, 1/80, 1/96, 1/112, 1/128, 1/133, 1/144, 1/160, 1/163 by setting the LCD duty
set command.
The display states such as LCD driving bias ratio, LCD Driving voltage, electric volume setting
value, boosting coefficient should be optimized to the selected LCD and display duty.
(26) DISCHARGE CIRCUIT
The discharge circuit of voltage(V
LCD
, V
1
~V
4
) stabilization capacitor is built in the
HM17CM4096
.
To discharge the capacitors, set the DIS register to “1” or set the RES terminal to “0”. When built-in
power supply circuit is used, built-in power supply circuit should be disabled before discharging of
the capacitor is executed. When external power supply(V

, V
OUT
) is used, external power
supply should be turned off before discharging of the capacitor is executed. Do not turn on the
internal power supply and external power supply (V

Usually RES terminal is connected reset terminal of CPU, so that the chip can be initialized
simultaneously with CPU.
HM17CM4096
should be initialized when the power is on.
