63 RDSDATA RDS data signal
input
This is the return signal input terminal of the initialize diode
matrix.
This is the RDS data signal input pin.
Please input the data signal from the RDS signal detection
part.
Data is read on the falling edge of the RDS clock.

64 RDSCLK RDS clock input
This is the RDS clock input pin.
Please enter the clock signal from the RDS signal detection
part.
Please input as accurate a clock as possible, because bit
synchronization detection by clock signal width is not
performed in the µPD17012GF-055.
