19、-3-1.

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

21、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 to finish a transaction un

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

23、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 all disables.) * Slave sends
