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. 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
(SH7710.IO) and then activate the HEW. After the I/O-register file is created, the MPU’s
specification 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 depending on its format. Note that, however, the E10A emulator does not
support the bit-field function.
Verify
In the [IO] window, the verify function of the input value is disabled.
13. Illegal Instructions
If illegal instructions are executed by STEP-type commands, the emulator cannot go to the
next program counter.
