Power ON
(0: Low, 1: High)
In no-clock mode (initial setting diode NOCLK = 1) or a mode in
which the clock is not counted during power off (initial setting diode
CTOFF = 1), the power consumption is reduced during power off.
Input pin for the ACC signal.
Input the signal as indicated in the table below.

PANEL Panel detachment Input pin used to detect whether the front panel has been detached. Input
detection input
The input of a high-level signal indicates that the front panel has
been detached.
71
REMIN Remote-controller
Remote-controller signal input pin.

Input
72
RDSCLK RDS clock input
RDS clock input pin. To this pin, input the clock signal from the
RDS signal detector section.
Because the µPD178016GC-051 does not detect bit
synchronization based on the width of a clock signal, the input
clock signal must be as accurate as possible.
Input
73
RDSDATA RDS data input
Input pin for RDS data. To this pin, input the data signal from the
RDS signal detector section.
Data is read at the falling edge of an RDS clock pulse.
