<p>Microcode controlled registers. </p>

|
|
<p>Most of the <a class="el" href="classao68000.html" title="ao68000 top level module.">ao68000</a> IP core registers are located in this module. At every clock cycle the microcode controls what to save into these registers. Some of the more important registers include:</p>
|
| 117 |
|
|
<ul>
|
| 118 |
|
|
<li>operand1, operand2 registers are inputs to the ALU,</li>
|
| 119 |
|
|
<li>address, size, do_read_flag, do_write_flag, do_interrupt_flag registers tell the <a class="el" href="classbus__control.html" title="Initiate WISHBONE MASTER bus cycles.">bus_control</a> module what kind of bus cycle to perform,</li>
|
| 120 |
|
|
<li>pc register stores the current program counter,</li>
|
| 121 |
|
|
<li>ir register stores the current instruction word,</li>
|
| 122 |
|
|
<li>ea_mod, ea_type registers store the currently selected addressing mode. </li>
|
| 123 |
|
|
