10. Loading Sessions
Information in [JTAG clock] of the [Configuration] dialog box cannot be recovered by loading
sessions. Thus the TCK value will be as follows:
⎯ When HS0005KCU01H or HS0005KCU02H is used: TCK = 2.5 MHz
11. [IO] Window
⎯ Customization of the I/O-register definition file
The internal I/O registers can be accessed from the [IO] window. The I/O-register
definition file for the SH72A2 and SH72A0 group does not include entries for all of the I/O
registers described in the hardware manual.
After the I/O-register definition file is created, the MCU’s specifications may be changed.
If each I/O register in the I/O-register definition file is at an address that differs from that
given in the hardware manual, change the I/O-register definition file accordingly. The I/O-
register definition file can be customized in accord with the prescribed format. Refer to
appendix E, I/O File Formats, in the SuperH
TM
Family E10A-USB Emulator User’s
Manual, when modifying or customizing the file of I/O-register definitions. However, the
emulator does not support the bit-field function.
A file of I/O-register definitions is stored in the location below.
\(Hew)\Tools\Renesas\DebugComp\Platform\E10A-USB\SH-2A\SH-2A_CUSTOM1
\IOFiles
The location of the Hew folder will vary according to where the customer has installed it.
As a default, the folder is installed in the C:\Program Files\Renesas\Hew folder.
⎯ Verify
In the [IO] window, the verify function of the input value is disabled.
12. Illegal Instructions
Do not execute illegal instructions with STEP-type commands.
13. Reset Input
During execution of the user program, the emulator may not operate correctly if a contention
occurs between the following operations for the emulator and the reset input to the target
device:
⎯ Setting an Event Condition
⎯ Setting an internal trace
⎯ Displaying the content acquired by an internal trace
⎯ Reading or writing of a memory
Note that those operations should not contend with the reset input to the target device.
14. MCU Operating Mode
Note that the emulator does not support the boot mode.
When starting up in the user boot mode, do not set a software breakpoint. Use an event point.
15. Writing Flash Memory Mode
Writing flash memory mode is not supported for the SH72A2 and SH72A0.
16. ID Code
ID codes are checked when starting up the emulator and when the CPU is reset (including in
the case of [Reset Go] operations).
