Position 6 of
SW3
determines whether
PF2
is connected to the
~OE
signal of
the ADV7183. When the switch “
OFF
”,
PF2
can be used for other opera-
tions, and the decoder output enable is held “
HIGH
” with a pull-up resistor.
Push Button Enable Switch (SW9)
The push button enable switch (
SW9
) positions 1 through 4 allow the user
to disconnect the drivers associated with the push buttons from the PF
pins of the processor. Positions 5 and 6 are used to connect the transmit
and receive the frame syncs and clocks of
SPORT0
. This is important when
the AD1836 video decoder and the processor are communicating in I
2
S
mode. Table 3-7 shows which PF is driven when the switch is in the “
ON
”
position.
