Abstract
A data processor (10) and method which provides show-cycles on a fast multiplexed bus (28) using two distinct modes of operation. A first mode of operation supports a standard show-cycle on a multiplexed bus for interface to a passive device such as a logic analyzer (100). A second mode of operation supports emulation tools (100) with real-time tracking of control functions using a multiplexed bus. During each of the modes of operation of the data processor (10), both read and write show cycles are supported and are consistently provided in a similar format.
