What does the SyncDrive “error” indicator mean in a receive com_blocks buffer_status variable?
A. This bit will be set when a receive CRC error occurs or when the receive buffer of the SCC itself suffers an overrun. An overrun will occur when the SCC is not being serviced rapidly enough. It is essentially a “horsepower” issue. Possible solutions include lowering the data rate, using DMA if possible (SyncDrive supports DMA only in the bit-synchronous mode), increasing the speed of the host computer, etc.
