15. [Memory] Window
If the following memory contents are displayed, they will be incorrect.
Word access from address 2n + 1
Longword access from address 4n + 1, 4n + 2, or 4n + 3
16. Scrolling Window During User Program Execution
Do not scroll the [Memory] and [Disassembly] windows by dragging the scroll box during
user program execution. This generates many memory reads causing the user program to stop
execution until the memory reads have been completed.
17. [I/O Registers] window
 Display and modification
• Do not change values of the User Break Controller because it is used by the emulator.
• For each watchdog timer and RCLK watchdog timer register, there are two registers to be
separately used for write and read operations.

• The watchdog timer operates only when the user program is executed. Do not change the
value of the frequency change register in the [I/O Registers] window or [Memory] window.
• The internal I/O registers can be accessed from the [I/O registers] window. However, note the
following when accessing the SDMR register of the bus-state controller. Before accessing the
SDMR register, specify addresses to be accessed in the I/O-register definition file
(SH7290.IO) and then activate the HDI. For details on I/O-register definition file, refer to the
Hitachi Debugging Interface User's Manual. Note that, however, the E10A emulator does not
support the bit-field function described in the Hitachi Debugging Interface User's Manual.
• Verify
In the [I/O Registers] window, the verify function of the input value is disabled.
