<PRE>Bits in each of the registers:
aaaaaass&nbsp; a: Tile map address&nbsp; s: SC size: 00=32x32 01=64x32
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 10=32x64 11=64x64</PRE>
To calculate the byte location where the tile map starts, shift the a (address)
bits left by 11 (multiply by 2048.)&nbs
