4. Floating Clerk Interrupt
Almost all operations are same as the normal clerk interrupt system. The only difference is the clerk
data is floating among ECRs in the IRC system. In order to use this system, IRC status check must
have been made with each ECR.
The following describes the key sequences and memory conditions on the master which picks up the
clerk's temporarily closed transaction data and the slave ECRs.
