Philips Semiconductors TEA5880TS

Integrated FM stereo radio IC for host processor tuning

[1] The frequency is decreased when increasing the content of this register.

Table 9: CTRL_A - (address 2h) bit description

Bit Symbol Description

14 to 11 - address bits

10 to 7 OUTPUT_

SELECT[3:0] selects an internal circuit as output for measurement purpose;

see Table10

6 STE_PMUTE mutes the stereo PLL when set to logic 1; this bit should be

setdur ing calibrationof the stereo decoder clock and should be

cleared during normal operation

5 DEM_PMUTE mutes the demodulator PLL when set to logic 1; this bit

should be set during calibration of the IF frequency and should

be cleared during normal operation

4 STE_INT_OFF# turns off the stereo integrator loop when set to logic 0

3 EN_MEAS# enables measurement when set to logic 0

2 AMUTE mutes the audio when set to logic 1

1 FM enables the FM circuitry when set to logic 1

0 - reserved for AM circuitry; should be written to logic 0
