mbus CSDB Clear


Continuously reading received data must be done at a pace to avoid receive buffer overflow. Overflow errors are reported by the mbus CSDB Clear when the incoming new data overwrites the data already in the buffer and waiting to be read. In such situation, the new data overwrites the unread ones resulting in data loss. Application must be designed to allow sufficient receive buffer size and do repeated calls to the mbus CSDB within short delay to avoid buffer overflow.

Overflow error can be handled by calling the mbus CSDB Clear once the error occurred. Clearing the overflow error allows to continue reading the received data using mbus CSDB
