* bit use | D | fou | FEOL | FEOL | FEOL | FEOL | UUUU | |
* bit number | 0 | 1 - 3 | 4 - 7 | 8 - 11 | 12 - 19 | 20 - 23 | 24 - 31 |
*
* device bits : D = Unused
* WB bits : f = frame done wb , o = wb buffer overflow ,
* u = wb buffer uncomplete
* vp bits : F = frame done , E = vsync even , O = vsync odd , L = sync lost
* plane bits : U = fifo underflow
