//This is gonna be the code for accessing the values in each of the mouse data busses
//firstly need to specify that the interrupt for mouse will start from address 00
//Do this inside the Verilog code for now

//RAM contents will look like this
/*
Mem[0] = 8'h00;
Mem[1] = 8'h01;
Mem[2] = 8'h02;
Mem[3] = 8'h03;
*/

//ROM also needs to have this
/*
ROM[8'hFF] = 8'h00;
*/

//To simulate the mouse without using memreadh
/*
//info about the interrupt location
ROM[8'hFF] = 8'h00;
//load a 01
