The Tearing effect line off (TEOFF) command ties the TE pin LOW.
Table 38 Tearing effect line off register bits
6.2.26
The Tearing effect line on (TEON) command turns the TE line of the display on.
The TE signal indicates the start of a super-frame (equals 16 frames). In 4 kbyte colour mode a whole super-frame is
needed to write full colour depth. In 8-colour mode the available colour depth is written in one frame. The tearing signal
goes HIGH when the last line of a super-frame is read. The HIGH time is 850 s (see Fig.21).
