With the PUPD[1:0] (power-up/power-down) bits the radio can be put in Standby mode.
Standby mode is defined as where the TEA5766UK has all supply voltages available but
the circuits are powered down via software (PUPD) or after power-on reset. The RDS part
can be turned off separately, using one of the PUPD bits. After a power-on reset or when
the TEA5766UK is in Standby mode, the TEA5766UK is still accessible via the control
interface, but takes only a limited amount of power from the supply. The software
programmable port maintains active to allow peripheral devices to be controlled. The
audio outputs are hard-muted.
In I
software (PUPD) the TEA5766UK is in Sleep mode. In this Sleep mode the TEA5766UK
is accessible via the bus, but the radio part is not active. The I
than in Standby mode.
When the supply voltages V
I/Os, the audio outputs and the reference clock input are in high-impedance state. The
power supplies can be switched on in any order.
After start-up of V
the registers will be set to their default values as shown in
effectively generated by V
high-impedance state (hard mute) and all other bits are set default according to the tables

Fully integrated RDS/RBDS demodulator, uses the reference frequency (32678 Hz) of the
PLL synthesizer tuning system. The RDS demodulator recovers and regenerates the
continuously transmitted RDS or RBDS data stream of the multiplex signal (MPXRDS)
and provides the signals clock (RDCL), data (RDDA) for further processing by the
integrated RDS decoder.
