(15) Electronic volume
This command sets a value of electronic volume “ ” for the V
display. See the function explanation in “Power supply circuit”, for detail.
(16) LCD bias set
This command selects the voltage bias ratio required for the LCD. This command is enabled when the voltage follower
circuit operates.
(17) Power saver
When the display all points ON command is executed when in the display OFF mode, power saver mode is entered, and
the power consumption can be greatly reduced.
This mode stops every operation of the LCD display system, and can reduce current consumption nearly to a static
current value if no access is made from the MPU. The internal states in the power saver mode is as follows:
Rev. 1.1a
• The oscillation circuit is stopped.
• The LCD power supply circuit is stopped.
• The LCD driver circuit is stopped and segment/common driver outputs output the V
• The display data and operation mode before execution of the Power saver command are held, and the MPU can
access to the DDRAM and internal registers.
