Values, symbols, and operators may be used together in analysis specification
expressions. For example, if the local symbol exists, the following is a valid
expression:
module.c:symb+0b67dh&0fff00h
However, you cannot add two symbols unless one of them is an EQU type symbol.
Emulation-Bus Analyzer Trace Signals
The emulation-bus analyzer has 80 channels available for capturing information:
64 of those channels are used for the instruction bus and data bus, and the
remaining 16 channels monitor other processor signals or
