Agilent Technologies E2413C MC68332 Preprocessor Interface. A bus interface unit within a processor ensures a delay period after the occurrence of a read operation to avoid bus contention on a multiplexed bus, When there is a requirement for a back-to-back read or write operation subsequent to the read bus cycle on a multiplexed bus it is important to allow devices, such as memory, sufficient time to reset after transmission of data. MC68332 Preprocessor Interface. timing analysis between any Motorola MC68332 target system and the. The user must set these switches appropriately before making
Development interface for a data processor A data processing system utilizing a multiplexed bus may encounter bus contention problems, wherein two different devices coupled to the bus, such as the microprocessor ("CPU") and an external memory, may simultaneously attempt to utilize the multiplexed bus (e.g., the CPU and the memory may both be attempting to transmit address and/or data information onto the multiplexed bus).

M68300 Family MC68332 - NXP Semiconductors To avoid the bus contention problem that occurs after a read bus cycle, i.e, prevent a next address on the bus until the bus is in a tri-state condition, one embodiment inserts idle clock cycles subsequent to a read but not subsequent to a write, The present invention avoids bus contention on a multiplexed bus while providing flexibility in interfacing with a variety of memory devices, and providing a flexible processor desn.selectively inserting idle periods after read operations until the first number of idle periods have passed, wherein the idle periods are inserted after read operations and not after write operations on said multiplexed bus;9. A bus is a set of hardware lines used for data transfer among the components of a computer system.

Mc68332 User's Manual Unknown The method as recited in claim 8, wherein said step of inserting said idle periods subsequent to said read operation when said period of no bus operations does not occur subsequent to said read operation comprises the step of inserting one or more clock cycles when a write operation or a second read operation is scheduled to be initiated during a bus cycle occurring immediately after said occurrence of said read operation.means for inserting the idle period on said multiplexed bus immediately subsequent to said completion of said read operation when said next bus operation has been requested by said processor to be initiated immediately subsequent to completion of said read operation;means for inhibiting insertion of said idle period on said multiplexed bus immediately subsequent to said completion of said write operation when said next bus operation has been requested by said processor to be initiated immediately subsequent to completion of said write period insertion means, the wait period insertion means ensuring that the first wait period has passed subsequent to detection of the first type of bus operation before beginning a next bus operation. A bus is essentially a shared hhway that connects different parts of the system--including the microprocessor, memory, and input/output ("I/O") ports--and enables them to transfer information.

An Introduction to the MC68331 and MC68332 The present application is related to the following U. patent application: "Method and Apparatus for Performing Multiplexed and Non-Multiplexed Bus Cycles in a Data Processing System", invented by Oded Yishay et al., having Ser. Typical buses have been desned so that one of lines carries data while another carries the addresses where specific data can be found, and yet other lines carry control snals to insure that the different parts of the system use the bus without conflict.

In contrast to this confuration, some computer systems utilize a multiplexed bus wherein the same lines of the bus carry both address and data information in a time domain multiplexed arrangement (i.e., address and data information are sent at different intervals).
