The RCV2 symbols and signal descriptions are listed in Table 2–16.
Table 2–16. RCV2 Symbols and Signal Descriptions
SYMBOL
SIGNAL DESCRIPTION
HSO
Horizontal synchronization output. As an output, RCV2 is asserted between BRCV and ERCV in every line
including VBI.
HSI
As an input, RCV2 is used for horizontal synchronization. Retriggers the horizontal counter.
CBNO
As an output, RCV2 is asserted between BRCV and ERCV from line FAL to LAL excluding VBI.
CBNI
As an input, RCV2 is used for composite blanking.
NLO
Output only, RCV2 generates a 4 LLC clock wide new line indicator at the beginning of a line to indicate to
the external logic to advance to the next line.

Where:
CRCM2
CREF modulation enable
0
CREF modulation is disabled
1
CREF modulation is enabled
When RCM2 is programmed as an active video output (ORCM2 = 1), CREF
modulation is enabled (CRCM2 = 1), and a 16-bit video input port is used, RCM2
is modulated by the internal CREF signal. The modulation is performed
before polarity control.
See Table 2–18 for programming information.
I/O setting of RCM2
0
RCM2 is set as an input pin (default).
1
RCM2 is set as an output pin.
Polarity setting of RCM2
0
RCM2 polarity is active high (default).
1
RCM2 polarity is active low.
Determines which signal is output to pin RCM1. Refer to Table 2–17.
Determines which signal is output to pin RCM1. Refer to Table 2–17.
