Function
FM Matrix Modes
Defines the dematrix function for the demodulated FM signal
bit [7:0]
In case of Automatic Sound Select, the FM Matrix Mode is set automatically,
i.e. the low-part of any I
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
bit [15:8] 00
I2S1 Prescale
I2S2 Prescale
Defines the input prescale value for digital I
bit [15:8] 00
SCART Input Prescale
Defines the input prescale value for the analog SCART input signal
