This is an I/O signal that is used for the touch panel. It uses the voltage applied to the X coordinate and
the voltage input to the Y coordinate to detect which coordinates on the touch panel are being pressed.
This is an I/O signal that is used for the touch panel. It uses the voltage applied to the Y coordinate and
the voltage input to the X coordinate to detect which coordinates on the touch panel are being pressed.
This is a general-purpose A/D input signal.
Operation clock input of modem interface block for CODEC
RING signal detect signal. This pin becomes active when the RING signal is detected.
Handset detect signal
On-hook relay control signal
Modem speaker mute control signal
CODEC reset signal
Serial input signal from CODEC
Frame synchronization signal from CODEC
Serial output signal to CODEC
Handset relay control signal
CODEC control signal
Clock output to CODEC
Use this pin for controlling power of CODEC and DAA. This signal is set as active when the power
supply of CODEC and DAA is ON.
