' This program runs concurrently in two different COGs. |

' |

' Each COG's program has different values implanted for front-porch lines and |
|||
' back-porch lines which surround the vertical sync pulse lines. This allows |
|||
' timed interleaving of their active display signals during the visible portion |
|||
' of the field scan. Also, they are differentiated so that one COG displays |
|||
' even four-line groups while the other COG displays odd four-line groups. |
|||
' |
|||
' These COGs are launched in the PUB 'start' and are programmed to synchronize |
|||
' their PLL-driven video circuits so that they can alternately prepare sets of |
|||
' four scan lines and then display them. The COG-to-COG switchover is seemless |
|||
' due to two things: exact synchronization of the two video circuits and the |
|||
' fact that all COGs' driven output states get OR'd together, allowing one COG |
|||
' to output lows during its preparatory state while the other COG effectively |
|||
' drives the pins to create the visible and sync portions of its scan lines. |
