Chapter 2. Functions

2-27

a. With trace enable bits

Tracing depends on the trace enable bit contents. Only addresses with a trace enable bit of 1 are
traced.

Trace enable bits specify tracing
for addresses 101H to 105H.

Code memory

b. Without trace enable bits

Tracing ignores the contents of the trace enable bits.

(3) Trigger trace

All instructions between start and stop triggers based on code memory addresses are traced—unless
limited with the trace enable bit option.

There are three possible trigger combinations:

a. Specifying both a start and stop address

Tracing starts when real-time emulation visits the former and stops when the program counter
(PC) hits the latter.

b. Specifying a start address only

Tracing starts when real-time emulation visits the former and continues until there is a break.

c. Specifying a stop address only

Tracing starts simultaneously with real-time emulation and stops when the program counter (PC)
hits the latter.

This example shows such tracing together with the trace enable bit option.

a. With trace enable bits

Tracing depends on the trace enable bit contents. Only addresses with a trace enable bit of 1 are
traced.
