LogiCORE Generic Framing Procedure (GFP) v1.3 - How does the core insert management frames when CHANx_GFP_REGSITER_B[16] and [17] are set?

Description

General Description: 

When the CSF timer expires, what type of management frames will the core insert if both CHANx_GFP_REGISTER_B[17] and [16] are set?

Solution

When the CSF timer expires, the core generates management frames for each type of management frame requested. If REGISTER_B[17] is set, the core inserts a loss of client signal. When REGISTER_B[16] is set, the core inserts a loss of character sync. When both bits are set, the core inserts two management frames back-to-back, one for each type of CSF request. In a multi-channel system, this is repeated for every channel sequentially as defined by the channel-specific registers.
