Transmission data format from Slave to Host There are two kinds of transmission data form from Slave shown below. 3-2-2-1. Form1: ACK/NAK ACK is a reply data from Slave when Sla

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

Form2: Status answer and Auto status feedback Status answers are reply data when Slave got an acceptable Request status or Command data from Host.

19、cted 3-3. The transaction sequences 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

20、answer by Status answer or NAK. *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 h

21、as to finish within 500ms when 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

22、a Status request . * Slave has 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

23、of layer 1 are assigned most 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. (T

24、he product default would be all 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.
