During execution of a flash ROM write request or parameter initialization request (this also applies to the "flash ROM request"
using the AD75 software package"), a transient transmission request such as the dedicated command (RIRD, RIWT) cannot
be accepted. A "response error" (error code: B404) will occur on the master station side if a transient transmission request is
executed during execution of a flash ROM write request or parameter initialization request.
If there is a possibility that a transient transmission request may be executed during execution of a flash ROM write request or
parameter initialization request, create a sequence program so that a transient transmission request will be executed again at
occurrence of a response error. (The processing time necessary for normal completion of flash ROM write or parameter
initialization is a maximum of 35s. Use this as a guideline for setting the retry count and response monitoring time.)
