Description

A HinawaFwFcp supports Function Control Protocol (FCP) in IEC 61883-1. Some types of transaction in 'AV/C Digital Interface Command Set General Specification Version 4.2' (Sep 1 2004, 1394TA) requires low layer support, thus this class has a code for them.

Any of transaction frames should be aligned to 8bit (byte). This class is an application of HinawaFwReq / HinawaFwResp.
