Function
IF output pin.
Output can be controlled by setting
the band switch data (P6).
IF output impedance is 75 W each
other.
When P6 data set 0, output pin is Pin
19 (IF output 1).
When P6 data set 1, output pin is Pin
21 (IF output 2).

If open or connected to V_CC2:
external input
25 TEST
When test mode set, this pin can
confirm X’tal divider signal and 1/2
counter signal.
This pin can be used at open.
