binary equivalent of 00000000000111. This mask write-protects lines 1, 2, and 3.

Function Yes
Usage
display.clear()
Details
This function switches to the user screen and then clears the display.
The
display.clear()
,
display.setcursor()
, and
display.settext()
functions are overlapped
commands. That is, the script does not wait for one of these commands to complete. These functions do not
immediately update the display. For performance considerations, they update the physical display as soon as
processing time becomes available.
