Function
FM Matrix Modes
Defines the dematrix function for the demodulated FM signal
bit[7:0]
In case of Automatic Sound Select = on, the FM Matrix Mode is set automati-
cally. Writing to the FM/AM prescale register (00 0E
In order not to disturb the automatic process, the low part of any I
sion to this register is ignored. Therefore, any FM-Matrix readback values may
differ from data written previously.
In case of Automatic Sound Select = off, the FM Matrix Mode must be set as
shown in Table 6–17 of Appendix B.
To enable a Forced Mono Mode for all analog stereo systems by overriding the
internal pilot or identification evaluation, the following steps must be transmitted:
1. MODUS with bit[0] = 0 (Automatic Sound Select off)
2. FM Presc./Matrix with FM Matrix = Sound A Mono (SAP: Sound B Mono)
3. Select FM/AM source channel, with channel matrix set to “Stereo” (transparent)
NICAM Prescale
Defines the input prescale value for the digital NICAM signal

I2S1 Prescale
I2S2 Prescale
Defines the input prescale value for digital I
bit[15:8]
SCART Input Prescale
Defines the input prescale value for the analog SCART input signal
