So what will happen if latch 74hc573 is not connected and movc or movx instruction are given The 8051 will continue to function as specified in its Datasheet and/or the so-called "bible" for the 8051. If you execute MOVC and/or MOVX instructions when there is no (properly configured) external memory, the results are undefined. How would MCU know whether ALE is connected to specific device or not. |

| Neither do I! | 01/01/70 00:00 | |

| Not allways... | 01/01/70 00:00 | |
| I hate to give ATMEL credit, ... but ... | 01/01/70 00:00 | |
| not with MOVX... | 01/01/70 00:00 | |
| Being more clear | 01/01/70 00:00 | |
| it seems perfectly reasonable to me ... | 01/01/70 00:00 | |
| Yes, some of them... | 01/01/70 00:00 | |
