Form1: ACK/NAK ACK is a reply data from Slave when Slave got an acceptable command data from Host. (ACK is sent to Host when Slave has no related stat

18、us by the Command.) Start character : , ACK : 06h, End character (CR) : 0Dh NAK is a reply data from Slave when Slave got an incorrect Command data, Status request data or some other data from Host. Start character : , NAK : 15h, End character (CR) : 0Dh 3-2-2-2. Form2: Status answer and Auto status

19、 feedback Status answers are reply data when Slave got an acceptable Request status or Command data from Host. Auto status feedbacks are send to Host data when a Slaves status is changed.

The transaction sequences and the regulations 3-3-1. The transaction sequences The tr

21、ansactions have three kinds of sequence. *A transaction is a Command from Host then Slave will be an answer by Status answer, ACK or NAK. *A transaction is a Status request from Host then Slave will be an answer by Status answer or NAK. *A transaction is Auto status feedback from Slave when a Slaves

22、 status changed. (If the auto status feedback is enabled.) 3-3-2. The transaction regulations The transactions have some kinds of regulation. * An answer (ACK, NAK or Status answer) transmittion by Slave has to finish within 500ms when got a Command or a Status request from Host. * Host must not tra

23、nsmit an another Command or Status request until it receives a answer by a previous Command or Status request or it passes a term of waitinng time from a finishing of previous transmission of a Command or a Status request . * Slave has to finish a transaction under 500ms when it sends Auto status fe

24、edback data. 3-3-3. Specification of Auto status feedback There are some specific regulations about Auto status feedback. * The product status has segmented into four layers of 1, 2, 3 and 4. * The status of layer 1 are assigned most kindly status to Host. (The statuses of layer 2 are assigned kindl

25、y status, the statuses of layer 3 are not so need status to Host and the statuses of layer 4 are probably no wished statuses.) * Each layer status can control transmit enable or disable by Host command. (The product default would be all disables.) * Slave sends auto status feedback by itself when th

26、e status is changed and if the status feedback is enabled. * The product defined and segmentationed layers are takeing in status list. 3-3-4.
