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.
