Checking the execution record of remote wakeup

When starting, a user program (including a remote wakeup program) may check via the I/O

ports whether the BHT remotely woke up at the last powering on and its operation was nor-

mally ended. (Refer to Appendix D, "I/O Ports.”)

Making use of the execution record, you may display an alarm message.

*This means that the BHT was cold-started, driven by System Mode, or initialized.
