used to form one frame. Each field
contains half the number of the total
amount of lines. The fields are
written in "pairs", causing line flicker.

Last Status
The settings last chosen by the
customer and read and stored in
RAM or in the NVM. They are called
at start-up of the set to configure it
according the customers wishes
