Automotive 40 x 4 LCD driver
6.1.1 Command: mode-set
The mode-set command allows configuring the multiplex mode, the bias levels and
enabling or disabling the display.
[1]
The possibility to disable the display allows implementation of blinking under external control.
[2]
The display is disabled by setting all backplane and segment outputs to VLCD.
[3]
Not applicable for static drive mode.
6.1.2 Command: load-data-pointer
The load-data-pointer command defines the display RAM address where the following
display data are sent to.
6.1.3 Command: device-select
The device-select command allows defining the subaddress counter value.
