1. A communication control apparatus comprising:
a communication apparatus configured to
save received data in a reception buffer,
execute transfer of the received data to a transfer destination buffer from the reception buffer,
erase the transferred data from the reception buffer, and
perform a hardware reset upon detecting an abnormality; and
a controller configured to
transmit data or a command to the communication apparatus,
check whether, after transmitting the data to the communication apparatus and after a lapse of time from (i) reception of the data by the communication apparatus to (ii) erasure of the data, the transmitted data are saved in the reception buffer, and
when at least some non-zero proportion of the transmitted data are saved in the reception buffer, transmit a command for causing the communication apparatus to execute a software reset instead of the communication apparatus performing the hardware reset upon detecting the abnormality.
