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 ROM 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
the C500 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. 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.

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.
