SRCV11
SRCV10
TRCV2
These 2 bits define signal type on pin RCV1; see Table 51
0 = horizontal synchronization is taken from RCV1 port (at bit SYMP = LOW) or from
decoded frame sync of “ITU-R BT.656”input (at bit SYMP = HIGH); default state after
reset
1 = horizontal synchronization is taken from RCV2 port (at bit SYMP = LOW)
0 = pin RCV1 is switched to input; default state after reset
1 = pin RCV1 is switched to output
0 = polarity of RCV1 as output is active HIGH, rising edge is taken when input; default
state after reset
1 = polarity of RCV1 as output is active LOW, falling edge is taken when input
When CBLF = 0.
If ORCV2 = 1, pin RCV2 provides an HREF signal (horizontal reference pulse that is
defined by RCV2S and RCV2E, also during vertical blanking interval); default state
after reset.
If ORCV2 = 0 and bit SYMP = 0, signal input to RCV2 is used for horizontal
synchronization only (if TRCV2 = 1); default state after reset.
When CBLF = 1.
If ORCV2 = 1, pin RCV2 provides a ‘composite-blanking-not’ signal, for example a
reference pulse that is defined by RCV2S and RCV2E, excluding vertical blanking
interval, which is defined by FAL and LAL.
If ORCV2 = 0 and bit SYMP = 0, signal input to RCV2 is used for horizontal
synchronization (if TRCV2 = 1) and as an internal blanking signal.
0 = pin RCV2 is switched to input; default state after reset
1 = pin RCV2 is switched to output
0 = polarity of RCV2 as output is active HIGH, rising edge is taken when input,
respectively; default state after reset
1 = polarity of RCV2 as output is active LOW, falling edge is taken when input,
respectively
