* In terms of physical addresses, if you consider physical address 0-&3ffff to be VRAM0 and physical address &40000-&7ffff to be VRAM1, then in P1 mode, the physical address equals logical address and in bitmap modes, every even address maps to &0-&3ffff (ever even is VRAM0) and every odd address maps to &40000-&7ffff (VRAM 1). This is described in the PDF.
* When reading 2bpp data with the POINT command the data appears to have undergone a circular shift so that the pixel you are interested in has it's value in the top 2 bits. e.g. X = 0 aabbccdd x = 1 bbccddaa x = 2 ccddaabb x = 3 ddaabbcc
