Asynchronous Read Method / Asynchronous Write Method

The following indicates an example of the main processing performed when the asynchronous read method (see
Section 9.3.2, Asynchronous Read Method) is used during reception processing and the asynchronous write method (see
Section 9.3.3, Asynchronous Write Method) is used during transmission processing.
When a timeout occurs, assess conditions based on the timeout error of CCS_M3ERR1_ERR2.ERR21 (error
information).
Has a timeout occurred?
