13. [IO] Window
⎯ Display and modification
Do not change values of the User Break Controller because it is used by the emulator.
The watchdog timer operates only when the user program is executed. Do not change the
value of the frequency change register in the [IO] window or [Memory] window.
The internal I/O registers can be accessed from the [IO] window. After the I/O-register
definition file is created, the MPU’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 customizing
the file of I/O-register definitions. Note, however, that the emulator does not support a bit-
field function.
A file of I/O-register definitions is stored in the location below.
\(Hew)\Tools\Renesas\DebugComp\Platform\E10A-USB\SH4A\SH4A\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.
14. Illegal Instructions
If illegal instructions are executed by STEP-type commands, the emulator cannot go to the
next program counter.
15. [Reset CPU] and [Reset Go] in the [Debug] Menu
In the [Configuration] dialog box, when [Auto] is set as [Reset Mode], the H-UDI reset is
issued at selection of [Reset CPU] or [Reset Go].
For the H-UDI reset, the watchdog timer except for the overflow counter and the clock
oscillator is not initialized.
To initialize all the resources, select [User] from the [Reset Mode] combo box in the
[Configuration] dialog box. At this time, if [Reset CPU] or [Reset Go] is executed, the reset
signal will be waited for being input from the user system.
16. Boot Mode
⎯ When the emulator is started up or the reset function of the CPU is used while the setting is
for the boot mode from the LBSC, a break in processing by the emulator occurs before
execution of the instruction at H’A0000000.
While the setting is for the boot mode from the SPI, a break occurs before execution of the
first instruction in the boot ROM.
Run the program in the boot ROM in accord with the procedure for executing programs.
⎯ If [Reset Go] is executed while a boot mode has been set, the address where execution of
the program starts depends on the setting for the boot mode.
