Complex mapping
The following 5 bytes are transferred bi-directionally between KL3681 and control:
Byte offset (without word alignment*) | Byte offset (with word alignment*) | Format | Input data | Output data |
|---|---|---|---|---|
0 | 0 | Byte | Status byte (SB) | Control byte (CB) |
1 | 2 | Word | DataIN0 | DataOUT0 |
3 | 4 | Word | DataIN1 | DataOUT1 |
*) Word alignment: The Bus Coupler places values on even byte addresses
Compact mapping (from firmware version 1C)
The following 4 bytes are transferred bi-directionally between KL3681 and control:
Byte offset | Format | Input data | Output data |
|---|---|---|---|
0 | Word | DataIN0 | DataOUT0 |
2 | Word | DataIN1 | DataOUT1 |
*) word alignment has no effect with compact mapping
