Software specifications

Figure 21. Write rds_int registers in SPI mode, reading 1 register

CSN

Note:

CLK

DATAIN

{1,rds_int[6:0]}

DATAOUT

rds_int[7:0]

The content of the RDS registers is clocked out on DATAOUT pin in the following order:

rds_int[7:0], rds_qu[7:0], rds_corrp[7:0], rds_bd_l[7:0], rds_bd_h[7:0], rds_ctrl[7:0],

sinc4reg[7:0], testreg[7:0], pllreg4[7:0], pllreg3[7:0], pllreg2[7:0], pllreg1[7:0], pllreg0[7:0].

For the meaning of each bit please refer to the relevant sections.

After 40 bit clocks the whole RDS data and flags are clocked out.
