3.19.5.1 PIP (Picture in Picture) Function
The TMP92CZ26A includes a PIP (Picture in Picture) function that allows a different
screen to be displayed over the screen currently being displayed on the LCD.
The PIP function manages the address space of display memory by dividing it into
“main screen” and “sub screen”. For the main screen, the display size and start address
are specified as in the case of the normal screen display. For the sub screen, the display
size and start address are also specified for determining the position and size of the sub
screen.
When the HOT point (upper-left corner) and segment/common size are set for the sub
screen and the PIP function is enabled by setting LCDCTL0 <PIPE> to “1”, the sub
screen is displayed over the main screen.
