3. Transmit the command:
4. Wait for nHOST_INT to assert.
5. Transmit and receive 0xFF until a byte other than 0xFF is received.
6. Receive response 0x00 (a byte other than 0xFF).
7. Receive the Error Byte and decode (0x02 is enumerated as RESET_POWERON).
8. Receive the Frame Terminator (0xA7).
9. Response 0x00 indicates the EM260 has reset and the Host should respond appropriately.
10. Deactivate Slave Select.
11. Since nHOST_INT does not assert again, there is no more data for the Host.

1. Activate nWAKE and activate timeout timer.
2. EM260 wakes up (if not already) and enables communication.
3. nHOST_INT asserts, indicating the EM260 can accept commands.
4. Host sees nHOST_INT activation within 3ms and deactivates nWAKE and timeout timer.
5. nHOST_INT deasserts immediately after nWAKE.
6. Activate Slave Select.
7. Transmit the Command 0x0A - SPI Protocol Version Request.
8. Transmit the Frame Terminator, 0xA7.
9. Wait for nHOST_INT to assert.
10. Transmit and receive 0xFF until a byte other than 0xFF is received.
