Toggle CS Pin
This property is of type True or false and can be referenced with the variable name ToggleCS.
Defines if the CS pin is left in the enabled state to speed up display operations.
Yes: Toggle the CS pin, other devices with their own CS pin can use the SPI bus.

Chooses which method to use when drawing to the gLCD component
The bitmap is the more common mode but may run slowly on some machines.
The point cloud should run faster but may use more memory.
