10. Receive the Frame Terminator (0xA7).
11. Response 0x00 indicates the SN260 has reset and the Host should respond
12. Deactivate Slave Select.
13. Since nHOST_INT does not assert again, there is no more data for the Host.

–
De-activate Slave Select.
nRESET toggles active low to reset the SN260.
nWAKE stays idle high between nRESET and nHOST_INT indicating the SN260
should continue with normal booting (do not enter the bootloader).
nHOST_INT asserts.
Activate Slave Select (nSSEL).
Transmit the command:
–
–
–
–
–
–
Wait for nHOST_INT to assert.
Transmit and receive 0xFF until a byte other than 0xFF is received.
Receive response 0x00 (a byte other than 0xFF).
Receive the Error Byte and decode (0x02 is enumerated as RESET_POWERON).
appropriately.
0x11: EZSP Parameter for this response (stackVersion). Note that this value may
vary).
0x30: EZSP Parameter for this response (stackVersion). Note that this value may
vary).
0xA7: Frame Terminator
0xFE: SPI Byte indicating an EZSP Frame
0x03: Length Byte showing the EZSP Frame is 3 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
0x06: EZSP Frame ID Byte indicating the callback command
0xA7: Frame Terminator
