communication mode flag and the readiness flag are used to communicate (because the stop condition and
start condition are processed by interrupt, the status is confirmed by the flag here).
At the time of sending, the send is repeated until the master device does not return a reply. If the master
does not return a reply, communication ends. At the time of receiving, the required amount of data is received.
If the communication ends, no reply is returned at the next data. Thereafter, the master device generates a
stop condition or a restart condition to exit the communication state.
