Abstract
The communication control apparatus includes a communication apparatus and a controller. The communication apparatus saves received data in a reception buffer, executes transfer of the received data to a transfer destination buffer from the reception buffer, erases the transferred data from the reception buffer, and interrupts the transfer upon detecting abnormality. The controller transmits data or a command to the communication apparatus. The controller checks whether the data are saved in the reception buffer after transmitting the data to the control apparatus, and transmits a command for causing the communication apparatus to execute a software reset when at least some proportion of the data are saved.
Claims4
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.
A communication method between:
- 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,
- the method comprising:
- checking by the controller 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
- transmitting by the controller, when at least some non-zero proportion of the transmitted data are saved in the reception buffer, 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.
