Changes

Port decoding NOTE: * Counters are reset to be confirmed0 at power on.* Counters are NOT reset to 0 when using bus reset (reset switch)

In Spectrum interface A10 chooses Decoding seems to be (some testing to confirm this):  I/O port for X,position is decoded as xxxx x0x1 xxx0 xxx0 (FBEE is normally used) I/O port for Y. On CPC interface position is decoded as xxxx x0x1 xxx0 xxx1 (FBEF is normally used) I/O port for Buttons is decoded as xxxx x0x0 xxx0 xxxx (FAEF is normally used) Confirmed connected:A10, A0 chooses X,Y.In Spectrum interface A4, A8 chooses buttons or directions. On CPC interface A8 alsochooses this.==== Movement ====

* Movement is accumulated so you only need to read the mouse status when you want e.g. once per frame.* Speed is 1 for slow movement of the mouse and 12 for very fast movement.* The position values aren't are not reset after reading.* The position values do not change if the mouse doesn't move in that is not moving * Position values wrap around e.g. when moving left with movement speed of 1, 0 wraps around to ff (0-1 -> ff)and when moving right with movement speed of 1, ff wraps around to 0 (ff+1->0) * To calculated the distance moved since last read subtract the new value read from the previous value read and AND with ff. The value is the amount of movement.
