7.15 Discharge Circuit
7.16 Scroll Function
Select a display duty ratio for the partial display from 1/8 to 1/128 using the DS (LCD
duty ratio) register.
Set the most suitable values for LCD drive bias ratio, LCD drive voltage, electronic
volume, the number of boosting steps, and others according to the actual LCD panel
and selected duty ratio in use.
The EM65101 has a built-in the discharge circuit, which discharges electricity from the
capacitors to provide stable power sources (V0~V4). The discharge circuit is valid
when the DIS register is set to “1.” When the built-in power supply is used, be sure to
set DIS=”1” after the power source is turned off (DCON, AMPON)=(0, 0).
This function specifies a portion of screen for scrolling. It sets the scroll top address,
scroll bottom address, scroll specified address, scroll mode of the scrolling area, and
scroll start address. Note that the scroll top address should be smaller than the scroll
bottom address, i.e.,
0 <= scroll top address, scroll bottom address, scroll specified address <= 127;
scroll top address <= scroll start address <= scroll bottom address.
Do NOT turn on both the built-in power source and the external power source (V0~V4,
VOUT) while DIS =”1.”
