The Recv Cmd has completed (C14=FALSE and WX2.3=OFF). If no Receive errors
occurred, data is moved into storage buffer. If error occurred and Receive
Timer has expired (C101=TRUE), data is not transferred to storage buffer. If
X4 (Send Input)=TRUE, C12 (Recv Cmd Seq) is disabled, C15 (Send Cmd Enable)
is set, and C107 (Recv Timer) is reset.
