TDA8204B

IBG : Standard I (don’t care)

FSn : Set to Auto NICAM (if NICAM fails, FM

mono is selected)

FN2 : Not used

SYN : Synthesizer selected

2 - Hardware Configurable Pins

2.1 - TDA8204B - PIN 6 - (RSW)

- as an output :

status of the RSW switch

- 0 = FM mono

- 1 = NICAM

- as an input :

- 0 = FM mono (forced)

2.2 - TDA8204B - PINS 34/35 - (SEL0/SEL1)

(see Figure 7)

- to select the language in case of bilingual opera-

tion

- selected value is related to LA0 and LA1

Figure 7

LA0 LA1

As the I2C bus is not used LA0 and LA1 = 0

(power-ON condition) / SEL0 = Q0, SEL1 = Q1

The 4 choices are summarized in the table below.

VII - 2.3. TDA8204B - PIN 25 - (MUTE)

- as an output :

status of the DAC

- 0 = unmuted

- 1 = muted

- as an input :

- 0 = unmute DAC (forced)
