The interlacing features of the c2p system keeps track of wether to draw the even or odd rows and columns. When you are using a double-buffered display, the toggling of even/odd rows and columns is simplified by a single call to Mc2pToggleDouble. This will handle the row and column interlacing in the context of working with a double-buffered display.
If either row interlacing or column interlacing in the c2p system are not switched on, they will simply be ignored. Note that when performing c2p interlacing in a double-buffered display it will take more than 2 frames to produce fully refreshed bitmaps.
Possible syntax:
Mc2pToggleDouble
