Abstract: A microcontroller is disclosed. The microcontroller includes a central processor unit (CPU) and a Flash program memory in communication with the CPU via an instruction bus. The microcontroller includes an on-chip debug (OCD) logic coupled to the CPU. The OCD logic containing logic that detects a zero opcode on an instruction bus between the CPU and the Flash program memory to provide a program breakpoint. This is an advantage over prior art in that any number of such breakpoints can be inserted into the Flash program memory, without requiring the memory to be erased. A system and method in accordance with the present invention provides a vastly improved support for program breakpoints in Flash program memory-based microcontrollers with a minimum increase in on-chip debug logic and complexity.

Abstract: The constriction plate of a fluidized bed incinerator is divided into a plurality of smaller perforated plate elements which are attached to an underlying frame structure with a mutual spacing corresponding to the heat expansion which the elements are subjected to during operation of the incinerator. The plate elements have bent rims so as to rest upon the support along sharp edges and are resiliently attached to the support. Attachment of the plate elements is effected by attachment means threaded through holes in the elements and embracing the bent area of the plate elements in the upper area thereof, the attachment means at their lower ends having a threaded area for screw connection to a resilient attachment piece. The attachment means may be arranged in pairs, each pair at their lower ends being attached to a common resilient attachment piece.
