Each of them is a 16-bit buffer to save the data received from the counterpart equipment, and

accommodates 512 bytes/256 words. The buffer structure is equivalent to that of the send

buffers.

The receive contents are cleared by the receive completion reset command (BFM #1 b2).

10.2.24 Spare Receive Buffers for Interlink Connection Mode <BFM #2257 to #2271>

Each of them is a spare buffer for the interlink connection in the case where the data exceeding
