See "§4-2. Frame Sync Protection" for the protection of the frame sync.
Note) This command bit register is shared with the $CX commands and the command bit set last is valid.
When the command bit is used in the existing state, set to the $CX commands. When the command bit
is used with the $AC address, make the settings same as for SFP3 to SFP0 set with the $CX
commands.
Command bit
SFP5 to 0
Sets the frame sync forward protection times. The setting range is 1F to 3F (Hex).
Processing
∗
During the period from 16th forward protection to the GFS rise, the sync protection window width (±6
channel clocks when WSEL = 0 and ±26 channel clocks when WSEL = 1) expands by 32 channel clocks
whenever the inserted sync is generated. GTOP rises when the window width becomes maximum (in excess
of 588 channel clocks).
Note) The sync forward protection times are not affected by SFP5 to SFP0.
Command bit
AVW = 0
Processing
Automatic expanding function of sync protection window width is turned off.
Automatic expanding function of sync protection window width is turned on.
AVW = 1
