			Example:

			Pressing left button only and releasing it will show &c1, one or more zeros and then &c0.
			If you press and hold down left button you will see &c1, and lots of zeros until you release then it shows &c0.

			The hardware will only give you the actual data that has changed, so if only moving left you will only get X offset values and no Y offset or button values.

This is the documentation about the '''PS/2 mouse connector''' of the [[SYMBiFACE II]] expansion card.

== Ports ==
* #FD10 (read only) read mouse status

== Usage ==
<pre>
Status byte
Bit 76543210
Use mmDDDDDD

m: Mode
D: Use-Data

If read and...

m = 00 -> no more data available, you can stop reading the status for a while
m = 01 -> D = X offset (signed); you will receive positive values, if the user
is moving the mouse to the right
m = 10 -> D = Y offset (signed); you will receive positive values, if the user
is moving the mouse upwards
m = 11 -> D[bit5] = 0 -> D[bit0] = left button
D[bit1] = right button
D[bit2] = middle button
D[bit3] = forward button
D[bit4] = backward button
D[bit5] = 1 -> D[bit0-4] = scroll wheel offset (signed)
</pre>

If '''m''' was not 00, then you should read the port again until you receive m=00.
If you don't receive a status for the mouse buttons, the last status is still
valid.
