Form1: ACK/NAK ACK is a reply data from Slave when Slave got an acceptable command data from Host. (ACK is

16、 sent to Host when Slave has no related status 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.

17、-2-2-2. Form2: Status answer and Auto status feedback Status answers are reply data when Slave got an acceptable Request status or Command data from Host. Auto status feedbacks are sent to Host data when a Slaves status is changed. Start character : Answer character : see “Status list” End character

The transaction seq

19、uences and the regulations 2-3-1. The transaction sequences The transactions 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 NA

20、K. *A transaction is Auto status feedback from Slave when a Slaves status changed. (If the auto status feedback is enabled.) 2-3-2. 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 whe

21、n got a Command or a Status request from Host. * Host must not transmit 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 ha

22、s to finish a transaction under 500ms when it sends Auto status feedback data. 2-3-3. 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

23、kindly status to Host. (The statuses of layer 2 are assigned kindly 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 a

24、ll disables.) * Slave sends auto status feedback by itself when the status is changed and if the status feedback is enabled. * The product defined and segmentationed layers are takeing in status list. 2-3-4.
