The implemented aWire responses are shown in the table below.
The AW has received the command successfully and performed the operation.
Table 31-50. ACK Details
The AW has received the command, but got a CRC mismatch.
Table 31-51. NACK Details
The JTAG idcode for this device.
Table 31-52. IDCODE Details
The data read from the address specified by the MEMORY_READ command. The last 3 bytes
are status bytes from the read. The first status byte is the status of the command described in
the table below. The last 2 bytes are the number of remaining data bytes to be sent in the data
field of the packet when the error occurred. If the read was not successful all data bytes after the
failure are undefined. A successful word read (4 bytes) will look like this:
