MO/ST
: When cleared, it is in Auto Mode.
When set, it is in Forced Monaural Mode.
Lo DX
: When cleared, full gain of the FM/TV RF amplifiers
When set, 40dB less gain than the full gain of FM/TV RF amplifiers.
OSC level gain : For FM, the oscillation level of the OSC can be reduced from the viewpoint of FCC.
For AM, to the contrary, the oscillation can be intensified so that the oscillator can run even
with a low impedance on the SW band.

STC
: When cleared, the OUT1 pin is switched to the general-purpose output port.
When set, the OUT 1 pin is switched to the ST output (stereo output). For stereo reception, the
pin is low.
PW
: When the AM, FM 1/32 and TV 1/8 modes are programmed, clear the PW bit.
When the TV 1/2 and FM are programmed, set the PW bit.
X’tal I1/X’tal I2 : For FM and TV, set X’tal I1 and X’tal I2 to 0 and 0.
For AM, the current of the X’tal block can be reduced from the viewpoint of X’tal harmonics
interference.
Note: When the standby mode is selected, be sure to reset X’tal I1 and X’tal I2, respectively, to 0 and 0, or the
oscillator will fail to run when the standby mode is released.
