If the XREADY signal is ignored (USEREADY = 0), then:
1. | Lead: | LR ≥ tc(XTIM) | |
LW ≥ tc(XTIM) |
These requirements result in the following XTIMING register configuration restrictions (no hardware to detect illegal XTIMING configurations):
XRDLEAD | XRDACTIVE | XRDTRAIL | XWRLEAD | XWRACTIVE | XWRTRAIL | X2TIMING |
---|---|---|---|---|---|---|
≥ 1 | ≥ 0 | ≥ 0 | ≥ 1 | ≥ 0 | ≥ 0 | 0, 1 |
Examples of valid and invalid timing when not sampling XREADY (no hardware to detect illegal XTIMING configurations):
XRDLEAD | XRDACTIVE | XRDTRAIL | XWRLEAD | XWRACTIVE | XWRTRAIL | X2TIMING | |
---|---|---|---|---|---|---|---|
Invalid | 0 | 0 | 0 | 0 | 0 | 0 | 0, 1 |
Valid | 1 | 0 | 0 | 1 | 0 | 0 | 0, 1 |
