|
|
// Purpose: This is a generic file that will need to be modified from one
|
| 8 |
|
|
// board implementation of the ZIP CPU to another. Specifically,
|
| 9 |
|
|
// this file defines where items are on a WISHBONE bus. In this
|
| 10 |
|
|
// case, the Zip CPU debug addresses are found at 0x060 and 0x61.
|
| 11 |
|
|
// The Zip Debugger needs to know these addresses in order to
|
| 12 |
|
|
// know what addresses to peek and poke to control and access the
|
| 13 |
|
|
// Zip CPU.
