MSCTRLn Bit Description R/W Initial State
Weave_in [31] Even and Odd fields can be read separately from a
complete progressive frame. The 1st frame reads even field
data and the 2nd frame reads odd field data. When 1st and
2nd frame operation finish, InputDMA is disabled. Both
Weave_in and Interlace_out should be set in simultaneous
frames. Also, it is recommended that pingpong address
should not be changed at Interlace even/ odd field
(BC_SEL field should 0) .
0 = Weave
1 = Normal
Note)
When using input rotator in Weave_in mode, output
horizontal size should be even value. Because vertical data
will be converted into horizontal one after rotating.
