• 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 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 emulator does not support the bit-field function.

• Verify

In the [IO] window, the verify function of the input value is disabled.

11. Illegal Instructions

If illegal instructions are executed by STEP-type commands, the emulator cannot go to the

next program counter.
