polarity of RCV2 as output is active HIGH, rising edge is taken when input; default
after reset
polarity of RCV2 as output is active LOW, falling edge is taken when input
pin RCV2 is switched to input; default after reset
pin RCV2 is switched to output
if ORCV2 = HIGH, pin RCV2 provides an HREF signal (Horizontal Reference Pulse
that is defined by RCV2S and RCV2E, also during vertical blanking Interval); default
after reset
if ORCV2 = LOW, signal input to RCV2 is used for horizontal synchronization only
(if TRCV2 = 1); default after reset
if ORCV2 = HIGH, 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 (PRCV2 must be LOW)
if ORCV2 = LOW, signal input to RCV2 is used for horizontal synchronization
(if TRCV2 = 1) and as an internal blanking signal
polarity of RCV1 as output is active HIGH, rising edge is taken when input,
respectively; default after reset
polarity of RCV1 as output is active LOW, falling edge is taken when input,
respectively
pin RCV1 is switched to input; default after reset
pin RCV1 is switched to output
horizontal synchronization is taken from RCV1 port; default after reset
horizontal synchronization is taken from RCV2 port
defines signal type on pin RCV1; see Table 21
