Operation when TP = TA = 1 (or when both the SK and DK pins are low)
Operation when TA = 1 (ON)
The RDS station having the PI (ON) code is searched in RDS memory and received.
If TP = TA = 1 cannot be read within four seconds of the station being received, the original station is restored and
received.
Operation when TP = TA = 1 is read from an RDS station with PI (ON)
CT is used to adjust the clock.
The time transmitted by a broadcast is the Coordinated Universal Time (UTC) as specified in the CCIR
By inputting time announcement information, the internal clock of the PD178016GC-051 is corrected using the
When initial setting diode CTADJ is set to 1, the clock is constantly being corrected by the input of broadcast time
Note that correction is made based on the broadcast time information, even when the clock is being adjusted using
Whether to enable adjustment of the clock using the time adjustment keys is specified using initial setting diodes

The state is changed from traffic information reception to traffic information standby if both TP and TA are not
1, or if TP and TA cannot be decoded for 30 seconds.
The original station is received if the traffic information reception state is set with TA = 1 (ON).

The original sound is restored.
If the volume was automatically changed when the traffic information was received, it is restored to its original
level.
If the volume was changed manually, however, it is not restored to its original level.
