Note:
• A/D/P mean an Analog terminal, Digital terminal, and Power terminal.
• DEF means reset state. H/L stand for output levels. Hz means high impedance and IN means input state (high impedance).
• Group categories are as follows :
HOST-Host interface, TSC-Touch screen interface, TEL-Telecom CODE, VB-Voice band CODEC, ETC-The other, POW-power supply.

This is a power supply terminal for an electret condenser mphone. Insert a 2-kΩ resistance
and more than 10µF electrolytic capacitor in series between this pin and the analog GND.

HZ(IN)
GPIO
These are general-purpose I/O ports. The selection of input and output and the output level
are set by the control resistor. After resetting, the ports are put in the input mode as a
default state. Pull down when not in use.
