11. Receive response 0x81 (a byte other than 0xFF), then receive the Frame Terminator, 0xA7.
12. Bit 7 is always set and bit 6 is always cleared in the Version Response, so this is Version 1.
13. Deactivate Slave Select.
14. Host begins timing the inter-command spacing of 1ms in preparation for sending the next command.
15. nHOST_INT asserts shortly after deactivating Slave Select, indicating a callback.
16. Host sees nHOST_INT, but waits for the 1ms before responding.
17. Activate Slave Select.
18. Transmit the command:
19. Wait for nHOST_INT to assert.
20. Transmit and receive 0xFF until a byte other than 0xFF is received.
21. Receive response 0xFE (a byte other than 0xFF), read the next byte for a length.
22. Stop transmitting after the number of bytes (length) is received plus the Frame Terminator.
23. Decode the response:
24. Deactivate Slave Select.
25. Since nHOST_INT does not assert again, there is no more data for the Host.
