Internal Trace Function: This function is activated by selecting the [Internal trace] radio button
in the [Trace type] group box of the [Trace mode] page. This function traces and displays the
branch instructions. The branch source address and branch destination address for the eight latest
branch instructions are displayed. See figure 6.10, [Trace mode] Page.

1. When an odd address is set, the next lowest even address is used.
2. A BREAKPOINT is accomplished by replacing instructions of the specified address.
3. During step execution, a BREAKPOINT is disabled.
4. Conditions set at Break Condition 2 are disabled when an instruction to which a

Accordingly, it can be set only to the internal RAM area. However, a BREAKPOINT cannot
be set to the following addresses:

which Break Condition 2 is satisfied.
execution is performed at the address before execution resumes. Therefore, realtime operation
cannot be performed.
Set the JTAG clock (TCK) frequency to less than the frequency of the SH7705 peripheral
module clock (CKP).
Set the AUD clock (AUDCK) frequency to 50 MHz or below for PCMCIA and PCI cards.
