1. One of two IF frequencies may be selected by using pin 4 of the ICSP programming
interface. If pin 4 is pulled High or left floating, then the first IF frequency is used. If pin 4 is
pulled to ground, then the second IF frequency is selected.
2. Each IF frequency can be independently programmed with IF frequency and offset (Add or
subtract). The first IF settings are programmed when pin 4 is pulled High or left floating, and.
the second IF settings are programmed when pin 4 is pulled to ground.
3. The default factory programming sets the floating pin 4 as the first IF configuration. If the IF
is zero, then the Up/Down setting is ignored.
4. In practice, pin 3 (GND) and pin 4 of the ICSP programming interface ICSP can be
connected to a 2P DuPont connector immediately adjacent or on the pins (See location circled
in red below). A switch can then be connected to select the appropriate IF setting.
