9.  For the AUD non-realtime trace, the written access may be executed again. If this is a problem 
on the user system, do not use the non-realtime trace. 
 
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 2.1, [Trace mode] Page. 
Notes:  1.  If an interrupt is generated at the program execution start or end, including a step 
operation, the emulator address may be acquired.  In such a case, the following 
message will be displayed.  Ignore this address because it is not a user program 
address. 
 
*** EML ***  
 
2.  If a completion-type exception occurs during exception branch acquisition, the next 
address to the address in which an exception occurs is acquired.   
 
3.  Trace information cannot be acquired for the following branch instructions: 
  The BF and BT instructions whose displacement value is 0 
  Branch to H'A0000000 by reset 
 
4.  The internal trace acquisition is not available when [User] is selected in the [UBC 
mode] list box of the [Configuration] dialog box. In this case, close the [Trace] 
window.

Notes on Using the JTAG Clock (TCK) and AUD Clock (AUDCK) 
1.  Set the JTAG clock (TCK) frequency to lower than the frequency of the SH7710 peripheral 
module clock (CKP). 
2.  Set the AUD clock (AUDCK) frequency to 50 MHz or lower for PCMCIA and PCI cards. 
2.2.5 
Notes on Setting the [Breakpoint] Dialog Box 
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.  
Accordingly, it can be set only to the RAM areas in CS0 to CS6 and the internal RAM areas.  
However, a BREAKPOINT cannot be set to the following addresses: 
  ROM areas in CS0 to CS6 
  Areas other than CS0 to CS6 
  Areas other than the internal RAM 
  An instruction in which Break Condition 2 is satisfied 
  A slot instruction of a delayed branch instruction
