69 / 201 page – 69 – CXD3029R $AC commands (preset: $AC0C001) Data 1 D3 1 D2 1 D1 0 D0 0 D3 AVW D2 0 D1 SFP5 D0 SFP4 D3 SFP3 D2 SFP2 D1 SFP1 D0 SFP0 D3 0 D2 0 D1 0 D0 0 AC (Sync expansion specification) Data 2 Data 3 Data 4 Command AVW: This bit sets the sync protection window width automatic expansion function. When "0", the sync protection window width automatic expansion function is off. When "1", the sync protection window width automatic expansion function is on. This setting is not affected by the sync forward protection times setting SFP5 to SFP0. ∗ The sync protection window width (±6 channel clocks when WSEL = 0, ±26 channel clocks when WSEL = 1) is widened 32 channel clocks at a time each time a sync mark is inserted during the interval from the 16th forward protection until GFS goes high. When the maximum window width is reached (when the window width exceeds 588 channel clocks), GTOP goes high. SFP5 to SFP0: These bits set the frame sync forward protection times. The setting range is from 1 to 3F (h). For details on frame sync protection, see "§4-2. Frame Sync Protection". ∗ Part of this command bit register is also used by $C SFP3 to SFP0. Of $AC SFP3 to SFP0 or $C SFP3 to SFP0, the command bit setting made last is valid. When using an existing status, set the value with $C SFP5 to SFP0. When using the $AC commands, set $AC SFP3 to SFP0 to the value set by $C SFP3 to SFP0. REFSEL2: This bit sets the refresh rate to DRAM. See the description of $A7 command REFSEL. SLIM1, 0: This bit sets the DRAM write speed limit value. D3 REF SEL2 D2 SLIM1 D1 SLIM0 D0 OV4 D3 OV3 D2 OV2 D1 OV1 D0 OV0 Data 5 Data 6 SLIM1 0 0 1 1 0 1 0 1 Up to 4.0 × speed write Up to 4.5 × speed write Up to 5.0 × speed write Up to 5.5 × speed write SLIM0 Write speed limit value ∗ ∗: preset OV4 to OV0 00000 to 11111 Can be set from 1 to 31 times. Limit value of speed violation number Preset value: 00001 Note) This command is valid when $A7X XWIH2 = 1. OV4 to OV0: This bit sets the limit value of the speed violation number for one GRSCOR which is reflected to XWIH. Note) • The violation speed is set with the $AC commands SLIM 1 and 0. • This command is valid when $A7X XWIH2 = 1. |
