7–0 | Physical Port # of Logical Port n | R/W | 1/0 | Used to re-map ports logically due to physical board constraints. Re-mapping is between any port of a 4-port group (1-4, 5-8). All ports of a group of four must be in OFF mode prior to receiving the port re-mapping command, otherwise the command will be ignored. By default there is no re-mapping. Each pair of bits corresponds to the logical port assigned. The selection per port is as follows: |
|||||
Re-Map Code | Physical Port | Package Pins | |||||||
0 | 0 | 1 | Drain1,Gat1,Sen1 | ||||||
0 | 1 | 2 | Drain2,Gat2,Sen2 | ||||||
1 | 0 | 3 | Drain3,Gat3,Sen3 | ||||||
1 | 1 | 4 | Drain4,Gat4,Sen4 | ||||||
When there is no re-mapping the default value of this register is 1110,0100. The 2 MSbits with a value 11 indicate that logical port 4 is mapped onto physical port 4, the next 2 bits, 10, suggest logical port 3 is mapped onto physical port 3 and so on. Note: Code duplication is not allowed – that is, Same code cannot be written into the remapping bits of more than one port – if such a value is received, it will be ignored and the chip will stay with existing configuration. Note: Port remapping configuration is kept unchanged if 0x1A IC reset command is received. NOTE After port remapping, TI recommends to do at least one detection-classification cycle before next port turn on. |
