void vdpmode (unsigned char mode, unsigned char sprites, unsigned char ie);

Configure VDP mode. This is a convenience routine to set VDP registers 1 & 2. The address of the various VDP data structures (registers 2 - 6) will also need to be configured.

mode =Bits to form BLANK (Inverted), M3, M2 and M1
0 - Graphics mode 1
1 - Text mode
2 - Multicolour mode
4 - Graphics mode 2
8 - Blank
sprites =0 - 8x8 sprites, magnification = 1
1 - 8x8 sprites, magnification = 2
2 - 16x16 sprites, magnification = 1
3 - 16x16 sprites, magnification = 2
ie =0 - Disable interrupt
1 - Enable interrupt (if enabled in CTC)
