2.2.3 Notes on Displaying the [Trace] Window

1. The AUD trace outputs the differences between newly output branch destination addresses and

the previously output branch destination addresses. If the previous branch destination address

is the same as the upper 16 bits, the lower 16 bits are output. If it matches the upper 24 bits,

the lower 8 bits are output. If it matches the upper 28 bits, the lower 4 bits are output. The

emulator regenerates the 32-bit address from these differences and usually displays it in the

[Trace] window. If the emulator cannot display the 32-bit address, it displays the difference

from the previously displayed 32-bit address.

2. When a completion-type exception occurs during exception branch acquisition, the next

address to the address in which an exception occurs is acquired.

3. When the [Halt] option is used from the popup menu in the [Trace] window, realtime

emulation is retained.

4. In the emulator, the maximum number of trace display pointers is 65535 lines (32767

branches).

However, the maximum number of trace display pointers differs according to the AUD trace

information to be output. Therefore, the above pointers cannot be always acquired.

5. When only one line is acquired by trace, the display data is not updated. In this case, open the

[Trace] window again.

2.2.4 Notes on Using the JTAG Clock (TCK)

1. When the JTAG clock (TCK) is used, set the frequency to lower than that of the system clock.

2. Do not set 20 MHz for the JTAG clock (TCK).
