2.2 Data Memory
The W7100 contains 64KB of embedded RAM, 64KB of TCPIPCore and the 256Byte of the Data FLASH. The Data FLASH is for user’s information such as IP address, MAC address, subnet mask and port number and so on. These memories are accessed by MOVX instructions only. The Figure 2.6 shows the “Data Memory” map of W7100. ------------- i suppose 0..255 is flash , 256..65535 is ram. both addressable by MOVX |

| Nope, both start at zero.... | 01/01/70 00:00 | |
| ? | 01/01/70 00:00 | |
| Yup, movx doesn't do it as far as i can tell.... | 01/01/70 00:00 | |
| Writing to flash - in general | 01/01/70 00:00 | |
| We cannot open the assembler instructions | 01/01/70 00:00 | |
| data flash API is through IAP | 01/01/70 00:00 | |
| documented quite concisely - but also contradictorily (!) | 01/01/70 00:00 | |
| but how does it matter? | 01/01/70 00:00 | |
| But it's not an omission! | 01/01/70 00:00 | |
| potentiality of users | 01/01/70 00:00 | |
Sad, but true - but WIZnet beware! | 01/01/70 00:00 | |
| So they do! | 01/01/70 00:00 | |

| Why do you believe that, Jan? | 01/01/70 00:00 | |
| hint is the debugging tool... | 01/01/70 00:00 | |
