ABSTRACT:
A bus device of a first type is designed to work with a bus devices of a second type. A bus device of the second type, when it is a slave in a bus transaction, issues an ACK if it can respond to the command on time, a NO ACK if it can't respond at all, a STALL if it expects to be able to respond with only a short delay, and a RETRY if it expects to be able to respond, but only after a long delay. Slave Bus devices of the second type also monitor the length of time that they assert the STALL signal, and if they assert if for more than a predetermined period, they replace the STALL signal with a RETRY. Bus devices of the second type, when they are master in a bus transaction, respond to a NO ACK by terminating a transaction in one way and to a RETRY by terminating the transaction in a different way. The bus devices of the first type provided by the present invention, although they are designed for use in conjunction with the second type bus devices, have no means for replacing a STALL with a RETRY when they are slaves in a bus transaction, and no means for responding to a NO ACK and a RETRY by terminating a transaction in a different manner when they are masters in a bus transaction.
