Data in Detail
P0 to 16:
N (divisor data P0: LSB, P16: MSB)
OUT1, 2:
When set, a high appears on the OUT pin.
When cleared, a low appears on the OUT pin.

Standby Mode
The tuner block, the PLL block and the
crystal oscillator: OFF
DO: Held at Low
1
Note: In standby mode, the X’tal I1 and X’tal I2 bits must be cleared. Otherwise, the oscillator does not run after the
TB2132FNG exits from the mode.
The OUT1 and OUT2 bits can be controlled by serial input data, even in standby mode.
DL:
When cleared, DO is in normal state.
When set, DO is held at low.
DO2:
When cleared, the OUT2 pin is switched to the general-purpose output port.
When set, the OUT2 pin is switched to the DO output.
IF GAIN:
When cleared, full gain of the FM IF amplifier.
When set, 2dB more gain than the full gain of the FM IF amplifier.
Divide by 16:
When cleared, FMOSC output: 1/32, TV OSC output: 1/8
When set, FMOSC output: 1/1, TV OSC output: 1/2

START:
IF count start bit
When cleared, maintain the count value.
When set, start measuring and decrease gain by 6dB in the FM/TV IF amplifiers after the count
value is reset. MUTE is turned on.
MUTE:
When cleared, MUTE is turned off.
When set, MUTE is turned on.
