3.1.5
The emulator incorporates a bus monitoring function that monitors and displays the contents of the accessed area
in HEW windows without stopping the program execution. Up to eight blocks of 256 bytes can be monitored.
In addition, the emulator can output trigger signals from external probe 2 (EXT2) when specified addresses (four
points max.) are accessed. Note that, however, some products do not support the bus monitoring function.
3.2
In most practical debugging applications, the program or hardware errors that you are trying to debug occur
under a certain restricted set of circumstances. For example, a hardware error may only occur after a specific
area of memory has been accessed. Tracking down such problems using simple PC breakpoints can be very
time-consuming.
The emulator provides a very sophisticated system for giving a precise description of the conditions you want to
examine, called the complex event system. This allows you to define events which depend on the state of a
specified combination of the MCU signals.
The complex event system provides a unified way of controlling the trace, break, and timing functions of the
emulator.
3.2.1
The event channels allow you to detect when a specified event has occurred. The event can be defined as a
combination of one or more of the followings:
Up to eight events can be combined into a sequence, in which each event is either activated or deactivated by the
occurrence of the previous event in the sequence. For example, you can cause a break if an I/O register is written
to after a specified area of RAM has been accessed.
3.2.2
The range channels can be set up to be triggered on a combination of one or more of the following:
The complex event system can be used to control the following functions of the emulator:

Address outside range
Read or Write or either
