Activate Slave Select (nSSEL).
Transmit the command 0x0A - SPI Protocol Version Request.
Transmit the Frame Terminator, 0xA7.
Wait for nHOST_INT to assert.
Transmit and receive 0xFF until a byte other than 0xFF is received.
Receive response 0x82 (a byte other than
0xA7.
Bit 7 is always set and bit 6 is always cleared in the Version Response, so this is
Version 2.
De-activate Slave Select.
Activate Slave Select (nSSEL).
Transmit the appropriate command:
–

–
–

–
Wait for nHOST_INT to assert.
Transmit and receive 0xFF until a byte other than 0xFF is received.
Receive response 0xFE (a byte other than 0xFF) and read the next byte for a length.
Stop transmitting after the number of bytes (length) is received plus the Frame
Terminator.
Decode the response:

0xFE: SPI Byte indicating an EZSP Frame
0x04: Length Byte showing the EZSP Frame is 4 bytes long
0x00: EZSP Sequence Byte (Note that this value should vary based upon previous
sequence bytes)
0x00: EZSP Frame Control Byte indicating a command with no sleeping
0x00: EZSP Frame ID Byte indicating the Version command
0x02: EZSP Parameter for this command (desiredProtocolVersion)
0xA7: Frame Terminator
0xFE: SPI Byte indicating an EZSP Frame
0x07: Length Byte showing the EZSP Frame is 7 bytes long
0x00: EZSP Sequence Byte (Note that this value should vary based upon previous
sequence bytes)
0x80: EZSP Frame Control Byte indicating a response with no overflow
0x00: EZSP Frame ID Byte indicating the Version response
0x02: EZSP Parameter for this response (protocolVersion)
0x02: EZSP Parameter for this response (stackType)
0xFF
), then receive the Frame Terminator,
