Enhanced Hooks Emulation Concept
The Enhanced Hooks Emulation Concept of the C500 microcontroller family is a new, innovative
way to control the execution of C500 MCUs and to gain extensive information on the internal
operation of the controllers. Emulation of on-chip memory based programs is possible, too.
Each production chip has built-in logic for the support of the Enhanced Hooks Emulation Concept.
Therefore, no costly bond-out chips are necessary for emulation. This also ensure that emulation
and production chips are identical.
The Enhanced Hooks Technology
together with an EH-IC to function similar to a bond-out chip. This simplifies the design and reduces
costs of an ICE-system. ICE-systems using an EH-IC and a compatible C500 are able to emulate
all operating modes of the different versions of the C500 microcontrollers. This includes emulation
of ROM, ROM with code rollover and ROMless modes of operation. It is also able to operate in
single step mode and to read the SFRs after a break.

Basic C500 MCU Enhanced Hooks Concept Configuration
Port 0, port 2 and some of the control lines of the C500 based MCU are used by Enhanced Hooks
Emulation Concept to control the operation of the device during emulation and to transfer
informations about the program execution and data transfer between the external emulation
hardware (ICE-system) and the C500 MCU.
