| Bit | J1 Pins | Description |
|
|
|
|
|
|
| Bit #0 (GPI0) | When this bit is a one (high), it instructs the debugger to use |
| |
|
|
| local Static RAM for its work page (i.e., variables, stack, vector |
|
|
|
| tables, etc.). This bit will be high when jumper is removed. |
|
|
|
|
|
|
| Bit #1 (GPI1) | When this bit is a one (high), it instructs the debugger to use |
| |
|
|
| the default setup/operation parameters in ROM versus the |
|
|
|
| user setup/operation parameters in NVRAM. This is the same |
|
|
|
| as depressing the RESET and ABORT switches at the same |
|
|
|
| time. This feature can be used in the event the user setup is |
|
|
|
| corrupted or does not meet a sanity check. Refer to the ENV |
|
|
|
| command (Appendix A) for the ROM defaults. This bit will be |
|
|
|
| high when jumper is removed. |
|
|
|
|
|
|
| Bit #2 (GPI2) | Reserved for future use. |
| |
|
|
|
|
|
| Bit #3 (GPI3) | Reserved for future use. |
| |
|
|
|
|
|
| Bit #4 (GPI4) | Open to your application. |
| |
|
|
|
|
|
| Bit #5 (GPI5) | Open to your application. |
| |
|
|
|
|
|
| Bit #6 (GPI6) | Open to your application. |
| |
|
|
|
|
|
| Bit #7 (GPI7) | Open to your application. |
