Commands
1. Display On/Off
Controls the on/off state of the LCD panel. The D0 bit sets the on/off state of the LCD display.
When a Display Off command is issued in the display fully on (all lit by All Display Pixels Lit On command) state, the
device goes to the power saving state.
2. Display Start Line Set
Sets the line address for the start of display from display data RAM. This address is set in two operations: first the upper
3 bits and then the lower 4 bits. Both the upper and lower bits can be set independently.
At reset, the display start line address is reset to 00H. The display can be scrolled by periodically changing the display
start line address with this command. In partial display mode, the content displayed can be changed without changing the
contents of display RAM by changing the address with this command.
See the functional description in the “Line Address Circuit” section for details.
