Notes: 1.
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. See figure 6.12, [Trace mode] Page. The
internal trace functions are also activated by selecting each check box on the [Branch trace] page.

When the trace display is performed during user program execution, the mnemonics,
operands, or source is not displayed.
When MMU settings are modified or when a user program is changed after GO
command completion before trace display, the displayed mnemonics, operands, or
source may not be correct.
The AUD trace function outputs the differences between newly output branch source
addresses and previously output branch source addresses. The window trace function
outputs the differences between newly output addresses and previously output
addresses. If the previous branch source 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 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.
If the 32-bit address cannot be displayed, the source line is not displayed.
In the SH7751R E10A emulator, when multiple loops are performed to reduce the
number of AUD trace displays, only the IP counts up.
In the SH7751R E10A emulator, the maximum number of trace display pointers is as
follows:
When HS7751RKCM02H is used: D'8191 to -0
When HS7751RKCI02H is used: D'32767 to -0
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.
If a TLB error occurs in the trace acquisition information display, the [Trace] window
displays the contents. However, mnemonics, operands, or source is not displayed.
