The transaction sequ

19、ences and the regulations 3-3-1. 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 NAK

20、. *A transaction is Auto status feedback from Slave when a Slaves 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

21、 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 has

22、 to finish a transaction under 500ms when it sends Auto status feedback 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 k

23、indly 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 al

24、l 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. 3-3-4.
