2 LSB for Scaling Factor for Cb data flow
The Cb data flow in the COR block is multiplied by the CB_SCALING factor.
(Each LSB of scaling factor = 1/64)
when CB_SCALING = 11 1111, the scaling factor = 1
when CB_SCALING = 00 0000, the scaling factor = 1/64
Scaling Factor for Cr data flow
The Cr data flow in the COR block is multiplied by the CR_SCALING factor.
(Each LSB of scaling factor = 1/64)
when CR_SCALING = 11 1111, the scaling factor = 1
when CR_SCALING = 00 0000, the scaling factor = 1/64
Enable for the pass-through mode
The pass-through mode allows (test) lines that are sent during the Vertical Blanking interval to be sent
captured by the line memory and reissued.
The OUTBEHAV_MOD1 selection bit is used to block the free run mode on the output clock when there is
no input video (HLOCK = 0).
0: Free run mode on the output clock when hlock = 0 (Default). The output data is blanked or not during the
no video state or the transient state according to the bits OUTBEHAV_BLANK1 and OUTBEHAV_BLANK2.
(See above)
1: The output clock follows the search performed by the input PLL. (This mode is mainly used for debug
reasons.)
The OUTBEHAV_BLANK1 and OUTBEHAV_BLANK2 selection bits are used to program the STV2310
behaviour when there is no input video (HLOCK = 0) or when there is an input video (HLOCK = 1) but the
vertical synchronisation is not yet acquired (VLOCK = 0). They are only operational when
OUTBEHAV_MOD1 = 0. This is the normal default mode.
OUTBEHAV_BLANK1 = 0, the output FIFO is read when HLOCK = 0
OUTBEHAV_BLANK1 = 1, the output data is blanked when HLOCK = 0
OUTBEHAV_BLANK2 = 0, the output FIFO is read when HLOCK = 1 and VLOCK = 0
OUTBEHAV_BLANK2 = 1, the output data is blanked when HLOCK = 1 and VLOCK = 0
