POWER Power output
The output is inverted each time the POWER key is pressed.
Use this pin to turn the radio on or off.
Connecting this pin to transistor switch RDSET enables power-on
and off of the radio.

LCD CS LCD chip select Output pin for the chip select signal
signal output
This pin is used as an output pin of the chip select signal for the
external LCD controller/driver (µPD7225).
When the output goes low, the external LCD controller/driver is
enabled.
CMOS
push-pull
output
Caution When the µPD7225 external LCD controller/driver is used, connect the C/D pin to the VDD pin at
the µPD7225.
