1. Activate Slave Select (nSSEL).
2. Transmit the appropriate command:
3. Wait for nHOST_INT to assert.
4. Transmit and receive 0xFF until a byte other than 0xFF is received.
5. Receive response 0xFE (a byte other than 0xFF) and read the next byte for a length.
6. Stop transmitting after the number of bytes (length) is received plus the Frame Terminator.
7. Decode the response:
8. Deactivate Slave Select.
