GENERAL COMMANDS
B.4.1
The Reset command resets the LCD display and PIC18F242 to their power-up state.
B.4.2
The Home command sets all coordinate variables to their home values and leaves the
display unchanged.
B.4.3
The HomeClear command clears the entire display and then sets all coordinate
variables to their home values.
