3D EFFECT FUNCTION
The 3D Pin controls the 3D effect function of PT2353. It toggles between turning the 3D effect function
ON or OFF. When the 3D effect function is enabled, the 3D LED is displayed. When the PO pin in low
state the 3D function and 3D LED is both inhibited.
POWER CONTROL
PK (Pin 14) is the PO Control Pin and is used to toggle between activating and deactivating the PO pin
(Pin 15). The power amplifier status (ON or OFF) may be controlled by connecting the external power
amplifier device to the PO Pin.
After the power supply is first applied to the VDD pin of PT2353, the output state for the PO and 3D pins
is LOW. During this state, all the control function keys are disabled, with the exception of the PK key.
When the PK key is pressed once, the PO is set to HIGH and all the control function keys are activated.
