Normal operation
The RDS-ID and demodulation circuits are cleared, and (in slave mode) the READY state and memory are cleared.
Master mode RDS-ID output (active high)
Slave mode Readout data ready output (active high)
RDS ID/READY pin
Note: The RDS-ID (READY) pin is an n-channel open-drain output, and data is read out by connecting a pull-up resistor.
