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 (SH7211.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.
