Preliminary Data Sheet
(9) Audio interface signals
Signal Name
I/O
Function
AUDIOIN
I
This is an audio input signal.
AUDIOOUT
O
This is an audio output signal. Analog signals that have been converted via the on-
chip 10-bit D/A converter are output.
(10)Touch panel interface signals
Signal Name
I/O
Function
TPX (0:1)
I/O
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.
TPY (0:1)
I/O
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.
ADIN (0:2)
I
This is a general-purpose A/D input signal.
(11)General-purpose I/O signals
Signal Name
I/O
Function
GPIO (0:3)
I/O
These are maskable activation factor input signals. After start-up, they are used as
ordinary GPIO pins.
GPIO (4:8)
I/O
These are general-purpose I/O pins.
GPIO (9:12)
I/O
These are maskable activation factor input signals. After start-up, they are used as
ordinary GPIO pins.
GPIO (13:14)
I/O
These are general-purpose I/O pins.

GPIO49
O
This function differs depending on the state of the RTCRST# signal.
<When RTCRST# = 1>
It can be used as a general-purpose output port.
<When RTCRST# = 0>
Set to the low level.
