Multiple address ranges

The VIC-II chip has 64 addressable registers. In the C64 memory map it is mapped to the range 0xD000…0xD3FF with it's registers repeated every 64 bytes.

This means that the following address ranges match those of the first 64 bytes at 0xD000…0xD03F:

Address Range		Equivalent
0xD040	0xD07F	Same as 0xD000…0xD03F
0xD080	0xD0BF	Same as 0xD000…0xD03F
0xD0C0	0xD0FF	Same as 0xD000…0xD03F
0xD100	0xD13F	Same as 0xD000…0xD03F
0xD140	0xD17F	Same as 0xD000…0xD03F
0xD180	0xD1BF	Same as 0xD000…0xD03F
0xD1C0	0xD1FF	Same as 0xD000…0xD03F
0xD200	0xD23F	Same as 0xD000…0xD03F
0xD240	0xD27F	Same as 0xD000…0xD03F
0xD280	0xD2BF	Same as 0xD000…0xD03F
0xD2C0	0xD2FF	Same as 0xD000…0xD03F
0xD300	0xD33F	Same as 0xD000…0xD03F
0xD340	0xD37F	Same as 0xD000…0xD03F
0xD380	0xD3BF	Same as 0xD000…0xD03F
0xD3C0	0xD3FF	Same as 0xD000…0xD03F

Notes:

RST8 in 0xD011 is bit 8 of the RASTER register in 0xD012.
Registers 0xD01E & 0xD01F cannot be written and are cleared on reading
RES in 0xD016 stops the VIC on the 6566. It has no function on the 6567 or 6569
Bit's with no label are not connected and return 1 on a read.
