Table 14-14. Responses that are supported
Response Name
0xA0 GenericResponse
0xA3 ReadMemoryResponse (used for sending responses to ReadMemory command
only)
0xA7 GetPropertyResponse (used for sending responses to GetProperty command only)
0xAF FlashReadOnceResponse (used for sending responses to FlashReadOnce
command only)
0xB0 FlashReadResourceResponse (used for sending responses to
FlashReadResource command only)
Flags: Each command packet contains a Flag byte. Only bit 0 of the flag byte is used. If
bit 0 of the flag byte is set to 1, then data packets will follow in the command sequence.
The number of bytes that will be transferred in the data phase is determined by a
command-specific parameter in the parameters array.
ParameterCount: The number of parameters included in the command packet.
Parameters: The parameters are word-length (32 bits). With the default maximum
packet size of 32 bytes, a command packet can contain up to 7 parameters.
14.3.7.5 Data packet
The data packet carries just the data, either host sending data to target, or target sending
data to host. The data transfer direction is determined by the last command sent from the
host. The data packet is also wrapped within a framing packet, to ensure the correct
packet data is received.
The contents of a data packet are simply the data itself. There are no other fields, so that
the most data per packet can be transferred. Framing packets are responsible for ensuring
that the correct packet data is received.
