2. WO: White Clip Off Mode
3. PSA: Power Save Mode
4. FA1~FA0: Audio intercarrier frequency
5. TPSG: Test Pattern Signal Generator Mode
6. N9~N0 (NA): Programmable divider data
1: Disables white clip function, e.g. when modulation characteristics for near-100% modulation are being
0: Enables white clip function (default).
1: Disables power saving (default).
0: Enables power saving. The device waits for data from the bus with all blocks other than the bus decoder
In Power Save Mode, the device retains all data values as long as V
again will trigger a power-on reset, causing all data values to be initialized.
1: Enabled
0: Disabled (default)
The RF VCO oscillation frequency is calculated using the following formula.

N = 512 × N9 + 256 × N8 + 128 × N7 + 64 × N6 + 32 × N5 + 16 × N4 + 8 × N3 + 4 × N2 + 2 × N1 + N0
The frequency varies in steps of 1 MHz. The +250-kHz term in the formula is hard-wired into the IC.
The divider N is obtained by subtracting 250 kHz from the frequency setting.
