⎯ Customization of the I/O-register definition file
The internal I/O registers can be accessed from the [IO] 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 (SH7285.IO or
SH7243.IO) and then activate the High-performance Embedded Workshop. 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 differs from addresses described in the hardware
manual, change the I/O-register definition file according to the description in the hardware
manual. The I/O-register definition file can be customized in accordance to its format.
However, the emulator does not support the bit-field function.
⎯ Verification
In the [IO] window, the input values cannot be verified.
13. Illegal Instructions
Do not execute illegal instructions with STEP-type commands.
14. 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.
15. Contention between the Change of the FRQCR Register and the Debugging Functions
The following notes are required for the user program for changing the multiplication rate of
PLL circuit 1 to change the frequency:
⎯ Avoid contention between the change of the FRQCR register in the user program and the
memory access from the [Memory] window, etc.
⎯ When the automatic updating function is used in the [Monitor] window or [Watch]
window, generate and set a break of Event Condition for an instruction immediately before
changing the FRQCR register. Contention will be avoided by generating a break and
executing the user program again.
For the change of the multiplication rate of PLL circuit 1 and the FRQCR register, refer to the
hardware manual for the MCU.
