1.1 Determining Silicon Revision
The device revision can be identified using the Revision mode of the Info command. This host microcontroller reads this information by issuing the Info command with the Revision mode (0x00) specified. The response for this mode is 8 bytes in length, with the fourth byte indicating the silicon revision number. The following table lists the required payload packet to be transmitted and the corresponding response payload for the B6 version of the TA100 device.
| Command Field | Parameters | Byte Values(1) |
|---|---|---|
| Info Command | Length: | 0x00 0x0A |
| Opcode: | 0x00 | |
| Mode: | 0x00 | |
| Param2: | 0x00 0x00 0x00 0x00 | |
| CRC: | 0xC2 0x70 | |
| B6 Response | Length: | 0x00 0x0D |
| Response: | 0x00 | |
| Data: | 0x00 0x02 0x00 0x07 0x00 0x00 0x04
0x00 | |
| CRC: | 0x97 0xC7 |
Note:
- Only the payload bytes are specified in the order sent or received. Additional command bytes associated with the applicable I/O protocols are not included.
