<p>Initiate WISHBONE MASTER bus cycles. </p>
|
| 125 |
|
|
<p>The <a class="el" href="classbus__control.html" title="Initiate WISHBONE MASTER bus cycles.">bus_control</a> module is the only module that has contact with signals from outside of the IP core. It is responsible for initiating WISHBONE MASTER bus cycles. The cycles can be divided into:</p>
|
| 126 |
|
|
<ul>
|
| 127 |
|
|
<li>memory read cycles (supervisor data, supervisor program, user data, user program)</li>
|
| 128 |
|
|
<li>memory write cycles (supervisor data, user data),</li>
|
| 129 |
|
|
<li>interrupt acknowledge.</li>
|
| 130 |
|
|
</ul>
|
| 131 |
|
|
<p>Every cycle is supplemented with the following tags:</p>
|
| 132 |
|
|
<ul>
|
| 133 |
|
|
<li>standard WISHBONE cycle tags: SGL_O, BLK_O, RMW_O,</li>
|
| 134 |
|
|
<li>register feedback WISHBONE address tags: CTI_O and BTE_O,</li>
|
| 135 |
|
|
<li><a class="el" href="classao68000.html" title="ao68000 top level module.">ao68000</a> specific cycle tag: fc_o which is equivalent to MC68000 function codes.</li>
|
| 136 |
|
|
</ul>
|
| 137 |
|
|
<p>The <a class="el" href="classbus__control.html" title="Initiate WISHBONE MASTER bus cycles.">bus_control</a> module is also responsible for registering interrupt inputs and initiating the interrupt acknowledge cycle in response to a microcode request. Microcode requests a interrupt acknowledge at the end of instruction processing, when the interrupt privilege level is higher than the current interrupt privilege mask, as specified in the MC68000 User's Manual.</p>
|
| 138 |
|
|
<p>Finally, <a class="el" href="classbus__control.html" title="Initiate WISHBONE MASTER bus cycles.">bus_control</a> controls also two <a class="el" href="classao68000.html" title="ao68000 top level module.">ao68000</a> specific core outputs:</p>
|
| 139 |
|
|
<ul>
|
| 140 |
|
|
<li>blocked output, high when that the processor is blocked after encountering a double bus error. The only way to leave this block state is by reseting the <a class="el" href="classao68000.html" title="ao68000 top level module.">ao68000</a> by the asynchronous reset input signal.</li>
|
| 141 |
|
|
<li>reset output, high when processing the RESET instruction. Can be used to reset external devices. </li>
|
| 142 |
|
|
</ul>
