Delayed Link Reset procedure on NACK reception unsupported #4
Description
The functionality of the NACK_RST_EN and NACK_RST_MODE signals is to provide the following scenarios :
| NACK_RST_EN | NACK_RST_MODE | Description |
|---|---|---|
| 0 | 0 | No action in case of NACK reception |
| 0 | 1 | No action in case of NACK reception |
| 1 | 0 | Link Reset after NACK reception |
| 1 | 1 | After NACK reception, wait to empty input buffers then Link Reset |
The IP does not currently support the scenario where NACK_RST_MODE and NACK_RST_EN are both asserted. If NACK_RST_EN is asserted, a Link Reset is performed as soon as a NACK is received. Otherwise, the reception of a NACK does not require any particular procedure.
The current status is as follows:
| NACK_RST_EN | NACK_RST_MODE | Description |
|---|---|---|
| 0 | 0 | No action in case of NACK reception |
| 0 | 1 | No action in case of NACK reception |
| 1 | 0 | Link Reset after NACK reception |
| 1 | 1 | Link Reset after NACK reception |
